Abstract

The utility model relates to the technical field of laparoscope appliance, and discloses ex-peritoneal knotter under guidance of the laparoscope, which comprises a handle (1) and an operational rod (2), wherein the front of the operational rod (2) is a hollow tube with a thread pulling hole (3) arranged on the tube wall, the wall in the front end of the thread pulling hole (3) is cut open along the axial direction, wherein a curve part (4) and a fixed part (5) are classified, wherein the curved part (4) adheres to the end surface of the fixed part (5), the corresponding site of the interior side of the curved part (4) is provided with a return spring (6). The utility model adopts the ordinary surgical thread instead of the titanium nip or the biological nip to solve the knotting issue in the vital organs, without influence on MRI examination in the future. Additionally, the utility model has a simple structure with low production cost, thereby greatly decreasing surgical cost.

Description

The outer wire twister of peritoneoscope cavity of resorption

Technical field:

This utility model relates to the laparoscopic instrument technical field, the outer wire twister of especially a kind of peritoneoscope cavity of resorption.

Background technology:

At present, laparoscopic surgery has been widely used in fields such as general surgery, thoracic surgery and gynecological, as emerging modus operandi, is adopted by numerous doctors and patient and approves.Because the Minimally Invasive Surgery otch is little, the intracavity knotting is simple effective unlike abdominal, and the ligation of significant points such as intra-abdominal organ such as blood vessel, cystic duct, appendix root has proposed higher requirement to operator.At present, the intracavity knotting is the position that need tie a knot at organ, with titanium folder on the titanium clamp pincers or biological folder, performs the operation minimum 2 pieces for every, and complicated operation then needs more.The titanium folder of performing the operation used belongs to metal material, though be best peritoneoscope metal surgical material, but after still having part patient operation foreign body reaction can appear, and, just be difficult to take out, even without antixenic patient in case use, if other disease takes place in operative region again, be in this zone when nuclear magnetic resonance, NMR MRI checks and can produce magnetic signal, the accuracy that influence is checked, the operation back stays the psychological burden that can't get over you for patient; Check that expense is too high though the biology of performing the operation used folder does not influence MRI, 1 piece of biology presss from both sides at least 300～400 yuans, even higher, if complicated operation, only biological expense of pressing from both sides just allows patient be difficult to bear.Also using a kind of wire twister at present both at home and abroad, is the disposable wire twister that is provided with noose in advance, costs an arm and a leg, even minor operation at least also will be used 2-3 noose.

Summary of the invention:

For overcoming the defective that exists in the above-mentioned prior art, the purpose of this utility model provides the outer wire twister of a kind of peritoneoscope cavity of resorption, uses the vitals ligation problem under the general surgery silk thread solution peritoneoscope, and expense is extremely low, and is safe and reliable.

For achieving the above object, this utility model adopts following technical scheme:

The outer wire twister of described peritoneoscope cavity of resorption, it is made of handle and action bars, and the action bars front end is a hollow tubular structure, and tube wall is provided with through wires hole, and the tube wall of through wires hole front end axially cuts, and is divided into bending section and fixed part, and the end face of bending section and fixed part pastes mutually; The inboard correspondence position of bending section is provided with return spring.

Owing to adopt aforesaid technical scheme, the utlity model has following superiority:

The outer wire twister of this peritoneoscope cavity of resorption under the prerequisite of assurance operation safety, without titanium folder or the biological intracavity ligation problem of pressing from both sides and using general surgery silk thread solution vitals, does not influence nuclear magnetic resonance check in the future, exempts patient's psychological burden; And it is simple in structure, and manufacturing cost reduces greatly, thereby has reduced the operation cost.

Description of drawings:

Fig. 1 is the front view of the outer wire twister of this peritoneoscope cavity of resorption.

Fig. 2 is Fig. 1 " A to " enlarged diagram.

Shown in the figure: 1-hands handle; The 2-action bars; The 3-through wires hole; The 4-bending section; The 5-fixed part; The 6-return spring.

The specific embodiment:

As shown in FIG., the outer wire twister of described peritoneoscope cavity of resorption, it is made of handle (1) and action bars (2), action bars (2) front end is a hollow tubular structure, tube wall is provided with through wires hole (3), the tube wall of through wires hole (3) front end axially cuts, and is divided into bending section (4) and fixed part (5), and bending section (4) pastes mutually with the end face of fixed part (5); The inboard correspondence position of bending section (4) is provided with return spring (6).

After anaesthetizing successfully, get umbilicus upper part otch gas making abdomen, the sleeve that advances to puncture is gone into mirror, then, advance main operation pincers and auxiliary operation pincers, the exploratory operation district, operation is done when needing the position of ligation, with handling tongs No. 7 or No. 10 general surgery silk threads or slip are walked around the position that needs ligation, as appendix root or neck of gallbladder, silk thread is pulled out abdominal cavity knotting, preferably surgical knot; Light bending section (4) of pressing wire twister action bars (2) front end, one end of silk thread is inserted in the tube wall of through wires hole (3), action bars (2) front end, bending section (4) homing under the effect of return spring (6), toe-in is at the front end of wire twister, an end knot of stretching silk thread then, or the two ends knot of tractive silk thread gently alternately, the handle (1) of holding wire twister pushes toe-in in the abdominal cavity, after toe-in pushed the abdominal cavity, urgent toe-in was pulled out wire twister; At the wire twister front end, second knot is made a call at the two ends of silk thread again, and repetitive operation pushes the abdominal cavity with second toe-in, can make a call to three knots and consolidate, and makes a call to 5～6 knots when using slip, cuts buttock line, finishes knotting.

Claims

1, the outer wire twister of a kind of peritoneoscope cavity of resorption, it is characterized in that: it is made of handle (1) and action bars (2), action bars (2) front end is a hollow tubular structure, tube wall is provided with through wires hole (3), the tube wall of through wires hole (3) front end axially cuts, be divided into bending section (4) and fixed part (5), bending section (4) pastes mutually with the end face of fixed part (5); The inboard correspondence position of bending section (4) is provided with return spring (6).
