Description

Laparoscope closing in type knot pusher

Technical field

The utility model belongs to medical instruments field, and in particular to a kind of laparoscope closing in type knot pusher.

Background technique

The Minimally Invasive Surgery that Hospitals at Present surgery uses is very common, and especially laparoscopic surgery is small to patient trauma, pain It is few, it is popular.

Laparoscope is a kind of medical instrument being widely used, for checking, diagnosing and treating abdominal cavity, the lesions such as pelvic cavity. Have compared with abdominal wound it is small, it is painful it is light, restore fast, few intercurrent disease, beauty, it is safe many advantages, such as.

Knotting is essential operating technology in abdominal surgery.Laparoscope knots compared with open surgery, because of abdomen Hysteroscope instrument is longer, and moving range is limited, and touch feedback weakens, and difficulty increases, especially deep part knotting.Single-hole laparoscopic knots Because the movement of instrumentation is more restricted, can opereating specification more reduce, and because laparoscope in operation and operation pincers are from same side To abdominal cavity is entered, the triangle principle of laparoscopic surgery operation is violated, operation difficulty is bigger.

Existing solution: some Titanium clips or absorbable titanium folder in clinic.

The shortcomings that existing method, is insufficient: in Titanium clip Preserving time abdomen, can generate stimulation to local organization, may cause The adhesion of local organization causes difficulty to second operation；And Titanium clip indwelling is in vivo, makes to postoperative imageological examination At interference, whether there is undesirable influence also to still have dispute at present human body.Absorbable titanium folder belongs to biological titanium folder, price compared with It is expensive.In laparoscopic surgery, when titanium presss from both sides deep location application, equally there is also operating spaces to limit to very much, usually can not accurately press from both sides Close respective organization.And titanium folder is easy to fall off, it is difficult when removing if position is improper after upper folder, for several inflammatory swelling, or The thick pipeline of person presss from both sides full problem there is also difficult.In some operations, titanium folder does not replace knotting.

Chinese patent (application number 201020206294.0) discloses a kind of " suturing knot guide for operation ", by handle, device Bar and device head composition, the device bar are rod-like structure, and the front of the device head is flat structure, and the device is procephalic flat A circular arc type groove is provided at structure, the handle is fixed on one end of device bar, and the device head is fixed on the other end of device bar.? In minimally invasive laparoscope body in suture operation, under the visual field of laparoscope forward by the circular arc type groove alignment line knot on suture knot pusher Push-tight, tightening it will not arbitrarily unclamp, the effective close and firm for guaranteeing operation stitching knot.

Chinese patent (application number 201620630871.6) discloses " a kind of anti-slip hysteroscope knot pusher of one-way fashion ", including Knot pusher main body, the front end of the knot pusher main body are provided with opening, and one end of the opening, which is connected with, to be only capable of to opening The flap valve that direction rotates.At tip added with mechanical structure, it is unidirectional valve structure, reduces cunning of the knot pusher in progradation De- phenomenon.

Utility model content

The purpose of the utility model is to provide a kind of laparoscope closing in type knot pushers.

The utility model is realized by following technical solution.

A kind of laparoscope closing in type knot pusher, the casing of gap is formed with including side wall entire body, and described sleeve pipe inner wall is equipped with For the inner tube that suture passes through, said inner tube is axially parallel with described sleeve pipe, and it is fan-shaped that more valves are provided on described sleeve pipe lower circumference Baffle, the baffle top offer through-hole, and the suture passes through the through-hole.

Beneficial effect

The utility model structure is simple, easy to make, low in cost, recycles, and reduces medical treatment cost；Titanium can be replaced Folder knots, and titanium folder is avoided to fall off to trouble caused by operation and to the injury of human body, and ligature securely, reduce operation risk and Operation wound.Particularly with the knotting of single-hole laparoscopic deep tissue, knot can be pushed into required position, avoid hysteroscope camera lens It " fights " with laparoscopic instrument, has saved operating time.

Specific embodiment

The utility model is described further with reference to the accompanying drawings and embodiments.

As shown in Figs 1-4, a kind of laparoscope closing in type knot pusher is formed with the casing 2 of gap 1, institute including side wall entire body It states 2 inner wall of casing and is equipped with the inner tube 4 that passes through for suture 3, said inner tube 4 and 2 parallel, 2 bottom of described sleeve pipe of axial direction of described sleeve pipe Provided circumferentially about to have more valve sector baffles 5,5 top of baffle offers through-hole 6, and the suture 3 passes through the through-hole 6.

The laparoscope closing in type knot pusher, inner tube 4 is at the gap 1 of casing 2.

The laparoscope closing in type knot pusher, it is vertical with 1 corresponding position of gap on 2 outer wall of casing to be equipped with handle 7.

Gap 1 in the utility model is parallel with the axis of casing 2 and extends in entire 2 side wall of casing.

Baffle 5 in the utility model is PET plastic material, and casing 2 and baffle 5 are integrally formed.

4 described sleeve pipe of inner tube, 2 tube wall in the utility model is connected, and is integrally formed.4 upper surface of inner tube and described sleeve pipe 2 Upper surface flushes, and 4 lower end of said inner tube extends to the junction of 2 bottom of casing and fan-shaped baffle 5.

3 length of suture in the utility model is 50-70cm, there is different silk thread models, can be needed according to operation to select It selects.

2 diameter of casing in the utility model is 5mm, 10mm and 12mm respectively, can be needed according to operation to select.

Handle 7 in the utility model is close to 2 upper surface of casing.

In operation, the utility model is used cooperatively with surgical forceps for abdominoscope 8.In application, selection has suitable types suture 3 The utility model, the utility model is fastened on the bar of surgical forceps for abdominoscope 8,3 lower end of suture is placed in abdomen by trocar Intracavitary, pulling makes it have certain length intraperitoneal, and intraperitoneal 3 one end of suture bypasses institutional framework to be ligatured, and one is hand-held Surgical forceps for abdominoscope 8, is knotted with winding method, i.e., itself rotation by line around on the body of surgical forceps for abdominoscope 8, surgical forceps for abdominoscope 8 clamp goes to 3 lower end of crack line again, and another hand pulls 3 upper end of suture simultaneously in vitro, keeps more valves of mouth under knot pusher fan-shaped Baffle 5 aggregates into tightening because pulling, and the bar by knot pusher along surgical forceps for abdominoscope 8 pushes down on, and surgical forceps for abdominoscope 8 is taken advantage of a situation back It is evacuated in knot pusher, the strength for the downward knot of baffle 5 tightened and polymerize simultaneously by 3 upper and lower side of suture completes deep part knotting. Second and third knot are completed in the reversed coiling of same method.

Laparoscope knotting is an extremely challenging operating technology, especially single-hole laparoscopic deep part knotting, some when It waits, titanium folder does not replace knotting, and can avoid pressing from both sides using Titanium clip or absorbable titanium using the utility model, reduces and produce to body Raw adverse effect, and can guarantee the reliability of knotting, the various situations occurred in art are flexibly coped with, knot can be pushed into institute Need position, avoid hysteroscope camera lens and laparoscopic instrument because angle problem it is intraperitoneal mutually " fighting " the problem of, saved hand The art time.

The utility model structure is simple, it is practical, safe, can recycle, is at low cost and convenient for universal, have very big The market space.
