Abstract

The utility model relates to a laparoscope intracavity suture knotter, which is composed of a control handle connected with a knotting mechanism, wherein one end of a sleeve is connected with a rotating handle, the rotating handle is connected with the control handle through a connecting block, the other end of the sleeve is connected with a fixed forceps mouth, a connecting rod passes through the sleeve, one end of the connecting rod is connected with the control handle, the other end is connected with a movable handle, one side of the sleeve is provided with a wiring groove, compared with the prior art, the utility model can conveniently carry out intracavity suture and ligation, can completely replace a metal clip or a biological clip in the operation process, simultaneously, enlarges the operation range of the laparoscope, compared with the traditional knotter, the product increases the suture function, the forceps mouth is changed into a flat bent needle head from a forked head, the forceps mouth is changed into a unidirectional opening, the stability is increased, the connecting rod is changed into an outer sleeve type, and can freely rotate, the abdominal cavity is changed into an abdominal cavity knot.

Description

Peritoneoscope intracavity stitching knotter

This utility model is a kind of peritoneoscope intracavity stitching knotter, belongs to technical field of medical.

Traditional open the abdomen cholecystectomy be with silk thread make material, seam is pricked cystic duct and blood vessel, the problem of this method is: operation need be opened abdomen, outside the chamber, sew up, bigger to patient's damage, recover slowly; The laparoscopic cholecystectomy that rises in the world is a kind of Minimally Invasive Surgery at present, because its damage is little, recover fast, so be subjected to the world, domestic extensive welcome and generally use, the problem that it exists is: need close cystic duct and blood vessel with Titanium folder or biological folder folder, the clamp material expense of each operation needs 200-600 unit, and clip is stayed in the human body, though the unlikely body that causes injures, but to the patient, certain mental burden is arranged, and certain influence is all arranged, simultaneously in the operation process for the inspection of X line and the inspection of nuclear magnetic resonance, NMR, for thicker cystic duct, closing with clip also has certain difficulty.

The purpose of this utility model is: a kind of peritoneoscope intracavity stitching knotter is provided, utilizes it in intracavity silk suture ligation, substituted metal folder or biological folder simultaneously, enlarge laparoscopically range of operation.

This utility model is to constitute like this: it connects knotting mechanism (7) by joystick (6) and constitutes, described knotting mechanism (7) is to form like this: an end of sleeve (1) connects handler (4), turning handle (4) is connected with joystick (6) by contiguous block (11), the other end of sleeve (1) is connected and fixed pincers and chews (2), connecting rod (5) passes sleeve (1), its end is connected with joystick (6), the other end connects adjustable clamp and chews (3), one side of sleeve (1) is provided with a connecting groove (9), fixation clamps chew (2) chew with adjustable clamp (3) mutually corresponding, fit, adjustable clamp is chewed the groove (10) that (3) is pasting on the sleeve (1) and is connected with connecting rod (5), and protective boot (8) is enclosed within an end of connecting rod (5).

Accompanying drawing 1 is a structural representation of the present utility model, accompanying drawing the 2, the 3rd, modular construction sketch map in addition of the present utility model.

Compared with prior art, the utility model can carry out suture ligature in the chamber easily, in surgical procedure Substituted metal folder or biological folder simultaneously, have enlarged laparoscopically range of operation, with traditional knotter fully Compare, this product has increased the stitching function, nose plier changes the flat curved syringe needle of holding into by a minute jaw, and nose plier is opened by two-way Change unidirectional opening into, increased stability, connecting rod changes into outer telescopic, and can rotate freely, and becomes the abdominal cavity Outer knotting is knotting in the abdominal cavity.

Embodiment of the present utility model: an end of sleeve (1) connects handler (4), turning handle (4) is connected with joystick (6) by contiguous block (11), the other end of sleeve (1) is connected and fixed pincers and chews (2), connecting rod (5) passes sleeve (1), its end is connected with joystick (6), the other end connects flexible handle (3), one side of sleeve (1) is provided with a connecting groove (9), fixation clamps chew (2) chew with adjustable clamp (3) mutually corresponding, fit, adjustable clamp is chewed the groove (10) that (3) is pasting on the sleeve (1) and is connected with connecting rod (5), protective boot (8) is enclosed within an end of connecting rod (5), during use, 4-7 silk thread with about 15 centimeter length inserts in the connecting groove (9) earlier, the right-hand end of connecting groove (9) is reserved about 1 centimeter length, with handler turn clockwise 720 the degree, this moment, line was around sleeve pipe two circles, wire twister is put into 10 centimetres of sleeves of peritoneoscope, send into the abdominal cavity by puncture sheath under the sword, wire-wound is crossed gallbladder or blood vessel, the reuse pincers are chewed and are clamped, left hand is held elastic separating plier and is put into the abdominal cavity by midclavicular line puncture sheath and clamp the right side of staying in connecting groove (9), ligation the end of a thread, to slide and strain on by wire twister around the silk threads of two circles, so just become the surgical knot of a standard; When sewing up knotting, suture needle is finished, removed earlier to seam, with wire-wound two circle tension knottings, also can obtain a Standard surgical binode with pincers, makes a call to a surgical knot again and strengthen.
