Device for laparoscopic summing catheters
(57) Abstract:The invention relates to medical technology, and more specifically to devices used in laparoscopy. The device consists of manipulation of the handle with a rotor tube placed therein a removable mandrel with adjustable angle of bending of the conductor, which allows the formulation of the catheter to the proper depth. The technical result is to create an optimal device for manipulation of the abdominal cavity, associated with the setting of the catheter when performing laparoscopic surgery. 4 Il. The invention relates to medical technology, and more specifically to devices used in laparoscopy.Known laparoscopic conductors catheter containing a working tube with a channel of the catheter, pneumatic valve, the retainer clip [1, 2].The disadvantages of these devices is the standard angle of bending of the conductor, which cannot be regulated, no rotor on manipulation of the handle, making it difficult to perform rotating movements of the conductor.The purpose of the invention is the creation of an optimal device for manipulation of the abdominal cavity, associated with the setting of the catheter when the execution key with the rotor, tube placed therein a removable mandrel with adjustable angle of bending of the conductor, which allows the formulation of the catheter to the proper depth.In Fig. 1 (side view) shows a device for laparoscopic holding the catheter of Fig. 2 - the same, top view; Fig. 3 is a General view of Fig. 4 - device operation.Device for laparoscopic holding catheter includes a manipulation knob with the rotor 1, the pneumatic valve 2, the working tube with a channel catheter 3, the removable rod for catheters with adjustable angle of bending of the conductor 4, the catheter 5.The device operates as follows. The catheter 5 is inserted into the working channel tube 3 through the pneumatic valve 2. On the opposite side of the working tube is screwed a removable rod for catheter 4, the rod through an extra hole put the catheter 5. The device is introduced into the abdominal cavity through an additional trocar, which is the dotted line in the wall, respectively, to the place of the alleged manipulation under control of the laparoscope. In place of the proposed catheterizable nadequate parietal peritoneum, the mesentery is stretched by fixing the gut clip endoergic. Using manipulation and kopiruyut tantalum bracket, after which the rod 4 is removed.Thus, applying the device for laparoscopists holding catheters reduces the run time of the method of catheterization, the task performances of the catheter to the root of the mesentery and small intestine for local summarizing drugs intraoperative and early postoperative treatment of intestinal obstruction.Information sources

Device for laparoscopic sum of catheters containing a working tube channel for catheters, pneumatic valve, characterized in that the device consists of manipulation of the handle with the rotor, the guide catheter is designed as a removable mandrel with adjustable angle of bending of the conductor, allowing catheter was installed to the proper depth.
FIELD: medicine, anesthesiology, resuscitation.
SUBSTANCE: one should perform puncturing of epidural space at Th12-L1 level. Through the lumen of puncture needle one should introduce catheter to move it cranially at the depth of 3 cm. After that one should inject 10 ml 05%-marcaine solution to perform repeated injections per 5.0 ml every 4 h during 1-8 d. The effect is achieved due to unloading minor cycle of circulation.
EFFECT: higher efficiency of therapy.
FIELD: medical engineering.
SUBSTANCE: device has silicon single-lumen tube as base. Device wall has longitudinal cuts near the olive at the same level. The cuts divide non-sticking nasogastric probe circumference into four equal sections. Capillary polypropylene tube for introducing solutions easily passes through the lumen. The tube has needle at the level of sections. It is attached to the non-sticking nasogastric probe olive with one end. Free end of the capillary tube movably passes through the non-sticking nasogastric probe wall from inside to outside 8-10 cm far from free end edge.
EFFECT: wide range of functional applications.
SUBSTANCE: method involves determining required foramen level. Needle is introduced at lumbar, sacral and thoracic segment level in paravertebral way with posterolateral access method and with anterolateral access at the cervical segment level. Tuochi 16-20 needle is applied. The needle is introduced 7-12 cm far from vertebral column median in the direction of intervertebral foramen at an angle of 50-80° to table surface in prone patient position at lumbar, sacral and thoracic segment level. The needle is brought in sliding in lateral direction after it has rested against joint facet. The needle is introduced towards the intervertebral foramen in dorsal patient position. Then, the needle slides from the transverse process in ventral direction. Short-term pain increase being the case, drugs are introduced.
EFFECT: enhanced effectiveness of treatment.
FIELD: medicine; medical engineering.
SUBSTANCE: method involves introducing operation end of the device into middle nasal passage, turning it in lateral direction, feeling deepening and compliant place in the lateral surface of middle nasal passage funnel and the operation end is introduced into the maxillary sinus through natural anastomosis. The device has S-shaped tube, pavilion for attaching syringe and pelot having mutually perpendicular surfaces. Distal end of the S-shaped tube is thickened and has cross-marks for denoting depth to which the device is introduced. Hemispheric mark is soldered to one of pelot surfaces, its direction being opposite to tube operation end direction. The tube operation end is soldered and has lateral openings.
EFFECT: reduced risk of traumatic complications.

SUBSTANCE: device has 150 cm long rubber double-lumen tube, hemostatic balloon placed 3.0-3.5 cm from the beginning of the rubber tube, holes in anterior and posterior portion of the hemostatic balloon and metal olive placed at the probe end. Marks are available on the probe at 45, 70 and 80 cm from its beginning.
EFFECT: no special equipment required for setting the device; available features for determining probe position; enabled X-ray control.
FIELD: medicine, oncology.
SUBSTANCE: the present innovation should be applied at adjuvant chemotherapy in case of tumors of central nervous system. Moreover, while carrying out lumbar puncture it is necessary to perform catheterization of subarachnoidal space. Moreover, one should daily sample liquor at the quantity of 10 ml to be incubated with chemopreparation in vitro for 30 min at 38 C. One should daily introduce chemopreparations upon autoliquor through catheter during the whole period of therapy course. The method enables to choose any mode and duration of endolumbar chemotherapy at its decreased toxicity.
EFFECT: higher efficiency of chemotherapy.
SUBSTANCE: method involves clipping aneurysms and setting two catheters into chiasmatic cistern and into internal carotid artery cistern. After having finished the operation, liquor is discharged concurrently from chiasmatic cistern and internal carotid artery cisterns in the amount of 5-7 ml at a rate of 30-40 ml/h. Two F90PvB Portex filters are sequentially attached to each catheter and the collected liquor is introduced at a rate of 30-40 ml/h and filtered. The cycle is repeated until one volume of circulating liquor is filtered. The process is repeated 6 h later in taking one filter off from each catheter and liquor filtration is continued through one filter. The liquor filtration sessions are repeated every other day depending on subarachnoid hemorrhage intensity. Total liquor filtration treatment is not to last more than 96 h long.
EFFECT: enhanced effectiveness of treatment.
