Description
Technical field
This utility model relates to a kind of operating theater instruments, relates in particular to a kind ofly to support for single-hole laparoscopic surgery provides stomach wall, and helps to improve the single-hole laparoscopic surgery service aisle stay pipe of operation efficient.
Background technology
Traditional Minimally Invasive Surgery part has solved that the abdominal wound surface is big, healing is difficult, the ugly problem of scar after the operation.Minimally Invasive Surgery from now on will be changed to the single hole Minimally Invasive Surgery by the porous Minimally Invasive Surgery gradually, and single hole is with respect to porous, and wound surface is littler, healing is easier, cicatrix is littler.
But the problem of single hole Minimally Invasive Surgery also is conspicuous: the work space of single hole operation is less; The difficulty of operation strengthens thereupon; Also higher to operation instrumentation, metathetical requirement; Apparatus passes in and out the probability that has increased traumatic infection repeatedly, and has prolonged operating time and patient's anesthesia duration, and operation risk strengthens.The structure of present single-hole laparoscopic surgery service aisle both domestic and external is mostly developed by the porous operating theater instruments, and operation technique is numerous and diverse, efficient is low, and sealing is not good enough.
Summary of the invention
For solve that existing single-hole laparoscopic surgery supporting sleeve exists defective, this utility model aims to provide a kind of simple in structure, easy to operate, and the single-hole laparoscopic surgery service aisle stay pipe of good airproof performance.
This utility model is realized above-mentioned purpose through following scheme:
The single-hole laparoscopic surgery service aisle is characterized in that: comprise stomach wall supporting sleeve and operating theater instruments sealed bladder, and said stomach wall supporting sleeve, bottom end face is domatic for cutting sth. askew, and the top is provided with retainer ring, and top one side of casing wall is provided with the gas access tube; Said operating theater instruments sealed bladder, the bottom opening place is provided with the elasticity loose collar that can be enclosed within on the said retainer ring, and Nang Ding is provided with apparatus and imports and exports.
Aforesaid single-hole laparoscopic surgery service aisle stay pipe also comprises the auxiliary propulsion rod, and said auxiliary propulsion rod hypomere is a spindle rod end, and the stage casing is provided with apical ring, and epimere is a lever.
Aforesaid single-hole laparoscopic surgery service aisle stay pipe, the bottom end face edge of said stomach wall supporting sleeve is provided with convexity, and top retainer ring outer wall is provided with groove.
The advantage of the single-hole laparoscopic surgery service aisle stay pipe of this utility model embodiment is: cooperates by stomach wall supporting sleeve, auxiliary propulsion rod and three separate parts of operating theater instruments sealed bladder, and simple and reasonable, be beneficial to the support stomach wall; The stomach wall supporting sleeve, bottom end face is domatic for cutting sth. askew, and can be rotated through rotating the gas access tube, helps guaranteeing maximum surgical work area area; During operation, good airproof performance between operating theater instruments sealed bladder and the stomach wall supporting sleeve, the gas that effectively reduces chamber mirror pneumoperitoneum is excessive; Import and export with apparatus on the operating theater instruments sealed bladder, all adopt medical grade rubber or have elastomeric macromolecular material, the displacement of the position of each apparatus improves operation technique efficient when being convenient to perform the operation.

The specific embodiment
Description of symbols in the Figure of description:
Stomach wall supporting sleeve 100, edge convexity 101, gas access tube 102, retainer ring 103, groove 104.
Operating theater instruments sealed bladder 300, elasticity loose collar 301, apparatus imports and exports 302.
Below in conjunction with accompanying drawing this utility model embodiment is elaborated.
As shown in Figure 1, the bottom end face of stomach wall supporting sleeve 100 is domatic for cutting sth. askew, and the top is provided with retainer ring 103, and retainer ring 103 outer walls are provided with cover groove 104, and tube wall top one side is provided with gas access tube 102.
As shown in Figure 2, auxiliary propulsion rod 200, hypomere are spindle rod end 203, and epimere is a lever 201, and the stage casing is provided with apical ring 202.
As shown in Figure 3, operating theater instruments sealed bladder 300 bottom opening edges are provided with elasticity loose collar 301, and Nang Ding is provided with apparatus and imports and exports 302.
When carrying out single-hole laparoscopic surgery, get into the abdominal cavity in the capable 3-3.5cm otch of stomach wall.
As shown in Figure 4, the spindle rod end 203 of auxiliary propulsion rod 200 is inserted in stomach wall supporting sleeve 100 pushes up retainer ring 103, after stomach wall is mentioned until apical ring 202; Hold lever 201 and slowly promote auxiliary propulsion rod 200 downwards, push abdominal wall tissue open by spindle rod end 203, stomach wall supporting sleeve 100 gets into the abdominal cavity simultaneously under auxiliary propulsion rod 200 drives; Contact with retainer ring 103 lower surfaces until abdominal skin; At this moment, stomach wall supporting sleeve 100 runs through stomach wall, is fixed between the abdominal wall tissue.
Extract auxiliary propulsion rod 200; In the pipe space just with the conducting of space, abdominal cavity, gas access tube 102 and pneumoperitoneum device are connected, operating theater instruments sealed bladder 300 bottom elasticity loose collars 301 are enclosed within the groove 104 of retainer ring 103 outer walls of stomach wall supporting sleeve 100; Operating theater instruments sealed bladder 300 just is sealed and matched with stomach wall supporting sleeve 100; Can effectively reduce the gas leakage of chamber mirror pneumoperitoneum, open the pneumoperitoneum device from gas access tube 102 to the intraperitoneal gas injection, gas is propped up the space, abdominal cavity;
As shown in Figure 5; From the apparatus import and export 302 of operating theater instruments sealed bladder 300 Nang Ding setting operating theater instruments being inserted stomach wall supporting sleeve 100 interior can beginnings performs the operation; Because operating theater instruments sealed bladder 300 is imported and exported 302 with apparatus and is all adopted medical grade rubber or have elastomeric macromolecular material; A plurality of operating theater instruments can realize position displacement like a cork not extracting under the state, help improving the operating efficiency of operating theater instruments; In the operation process, can also drive 100 rotations of stomach wall supporting sleeve,, satisfy requirements of operation with the adjustment surgical work area through rotating gas access tube 102.
After operation finishes, operating theater instruments is imported and exported 302 from apparatus extract out, directly stomach wall supporting sleeve 100 is slowly extracted from the abdominal cavity together with operating theater instruments sealed bladder 300 simultaneously, the operation of promptly feasible pass abdomen.
The single-hole laparoscopic surgery service aisle stay pipe of this utility model embodiment, rational in infrastructure, simple to operate, good airproof performance, for the operating efficiency that improves operating theater instruments with reduce the traumatic infection probability and be of great importance.
Need to prove; Above content is only in order to explain a kind of technical scheme of this utility model; But not to the restriction of this utility model protection domain; The simple modification that those skilled in the art carries out the technical scheme of this utility model perhaps is equal to replacement, does not all break away from the essence and the scope of this utility model technical scheme.
