Detachable stomach clamp

The creation department is related to medical appliances, in more detail, especially a gastric clamp capable of pinching the stomach out of a narrowed gastric sac and having the advantages of easy assembly and disassembly; placing the gastric compartment clamp can make the diseased state Obese patients significantly reduce their food intake and achieve weight loss.

In view of the irreversibility of traditional gastric compartment surgery, complicated surgical procedures, long operation time, complicated wound leakage, bleeding, infection, etc., the creator of the case designed the "stomach spacer" No. 091219707 and obtained the patent. The invention relates to a stomach compartment fixture, characterized in that: the fixture is made of a material that can be implanted into a human body, and the body is folded once to form a fixture space and a fixture opening therebetween. Each of the sides of the jig is provided with an arc convex portion which is raised in the opposite direction of the jig space; the jig opening is used for introducing the front and rear stomach walls in the jig space for clamping the distance between the front and rear stomach walls in the fixed jig space Inside, the front and rear stomach walls are closed in the state of no compression force, and the clamping portion still maintains blood flow; the clamp is obliquely attached to the upper part of the stomach, and the stomach is separated from the clamp. The stomach sac, and the portion corresponding to the arc convex portion forms a gastric sac outlet. The fixture performs laparoscopic surgery to perform the physical compartment of the stomach. The operation time is short, the abdominal wound is small, and there is no risk of leakage of the surgical wound in the traditional gastric compartment. The stomach wall can maintain a considerable blood circulation, so that it can be disassembled and restored at any time. The reversibility of the stomach structure.

However, in the actual application, the wire must be wrapped around the opening of the jig to form a jig having the force of maintaining the space of the jig, and the fixing technique of the wire wrapping is difficult to perform, which may prolong the operation time. Moreover, the other end of the body relative to the opening is of a fixed size and a spacing, and only a single size cannot be fully applied to all users. Therefore, the creators of this case have further actively developed and improved to provide a more complete and better stomach clamp.

In view of the above shortcomings, the present invention proposes a detachable stomach clamp, which is hooked between two clamping members to form a positioning, and can be conveniently clamped to the stomach during surgery to form a reduction. The stomach pouch makes the installation method easier and easier. The method of removing from the stomach is also quite convenient, and will not cause damage to the gastric sac. Further, a relatively stable fixing effect is provided, and the adverse effects such as sliding and displacement are not caused by factors such as long-term use.

A detachable stomach clamp comprising:

a first clamping member having a first hooking portion at each end thereof;

a second clamping member having a second hooking portion at each end thereof;

At least two hooks are respectively provided with a first hook portion and a second hook portion at the two ends, and the hook portions are respectively hooked on the first and second grip members by the first and second hook portions a second hooking portion, which is surrounded by a jig space, wherein the first clamping member is provided with a bulging portion protruding to the outside of the jig space;

The main purpose of the present invention is that the first and second clamping members can be fixed in an oblique or lateral direction in front of and behind the stomach wall by using the hooks, and the stomach is used to make the stomach The Ministry isolates a narrowed gastric sac that communicates with the stomach tube (the cardia). Furthermore, a gastric sac outlet is formed at the portion of the anterior and posterior stomach wall corresponding to the bulge to limit the maximum size of the gastric sac outlet by the ridge. When the hooks are installed, the first and second clamping members can be quickly positioned in the stomach by hooking and fixing, the procedure is simple, the operation time is short, the abdominal wound is small, and the amount of bleeding is small. The pain is reduced, the chance of infection is reduced, and there is no risk of surgical wound leakage. Furthermore, the stomach part of the clamp clamped in this case is the physical closure of the anterior and posterior stomach walls, and there is no structural tissue damage, and the stomach wall can still maintain a considerable blood circulation, avoiding adverse necrosis or degeneration of the stomach wall blood. In the case of disassembly, it is also convenient to detach the stomach, which can reduce the operation time and reduce the adverse effects caused by long-term use.

The second purpose of the creation is that the first hook portion and the second hook portion are formed by bending the end portion of the hook member to the inner side, so that a length between the first hook portion and the second hook portion is smaller than the length of the hook portion. The opening makes it difficult for the hook to escape from the opening after the hook is hooked with the first and second clamping members.

Another purpose of the creation is that since the first and second clamping members are separated and disposed, the hooks can be made into several different sizes and lengths, so as to suit different thickness requirements of the stomach, suitable The size of the hook can effectively adjust the force applied to the stomach by the first and second clamping members, so that the front and back stomach walls are closed in the state of no/low compression force, ensuring that the clamping portion maintains blood flow. It effectively prevents the stomach tissue from being necrotic due to excessive clamping.

For the convenience of the description, the central idea expressed in the column of the above novel content is expressed by a specific embodiment. Various items in the embodiments are depicted in terms of ratios, dimensions, amounts of deformation, or displacements that are suitable for illustration, and are not drawn to the proportions of actual elements, as set forth above. In the following description, like elements are denoted by the same reference numerals.

Referring to FIGS. 1 to 3 , a detachable stomach clamp 1 includes a first clamping member 10 , a second clamping member 20 , and at least two hook members 30 .

The first clamping member 10 is respectively provided with a first hooking portion 11 at both ends thereof. In a preferred embodiment, the first clamping member 10 is made of stainless steel wire and is hollow. Framed

The second clamping member 20 is respectively provided with a second hooking portion 21 at both ends thereof. In a preferred embodiment, the second clamping member 20 is made of stainless steel wire and is hollow. Framed;

The hooks 30 can also be made of stainless steel, and a first hook portion 31 and a second hook portion 32 are respectively disposed at the two ends. The first hook portion 31 and the second hook portion 32 are hook members 30. The end portion is bent to the inner side to form an opening 33 between the first hook portion 31 and the second hook portion 32 that is smaller than the length of the hook member 30. The hooks 30 are hooked by the first hook portion 31 and the second hook portion 32 to the first clamping member 10, the first hooking portion 11 of the second clamping member 20, and the second hooking portion 21, respectively. The first clamping member 10 is further provided with a ridge 12 protruding outward of the clamp space 40.

After clarifying the detailed structure of the above case, the following is a detailed explanation of the action principle of the case:

As shown in FIG. 4, a hook 30 can be hooked to the first hooking portion 11 and the second hooking portion 21 at one end of the first clamping member 10 and the second clamping member 20, so that the first A wide angle of opening between the clamping member 10 and the second clamping member 20 is provided to facilitate introduction of the front stomach wall 91 and the posterior stomach wall 92 from the open end into the clamp space 40, and finally the other hook member 30. Fastened at the end (as shown in Figure 5) to enclose the clamp space 40 to form a closed space. Thereby, the hooks 30 can quickly fix the first clamping member 10 and the second clamping member 20 in an oblique or lateral direction to the stomach wall 91 and the posterior stomach wall 92 before the stomach portion 90, and utilize the first A clamping member 10 and a second clamping member 20 sandwich the front stomach wall 91 and the posterior stomach wall 92 at the clamp space 40, whereby the physical closing action of the front stomach wall 91 and the posterior stomach wall 92 can isolate the stomach 90 A narrowed gastric sac 94 (shown in Figures 2 and 3) is provided in communication with the stomach tube 93 (the cardia).

Furthermore, as shown in FIG. 5, since the ridge portion 12 protrudes toward the outside of the jig space 40, it has a large space, so that the stomach wall 91 and the posterior stomach wall 92 have sufficient accommodation space without physical closure. A stomach capsule outlet 95 is formed at a portion of the anterior stomach wall 91 and the posterior stomach wall 92 corresponding to the ridge portion 12, and the maximum size of the gastric sac outlet 95 can be restricted by the ridge portion 12, wherein the gastric sac outlet 95 is connectable To the pyloric tube 96.

Thereby, the volume limitation of the reduced gastric capsule 94 can effectively control the food intake, and can effectively prevent the intake of a large amount of food. And the gastric sac outlet 95 of the narrowed stomach pouch 94 is connected to the pyloric tube 96, and the ridge portion 12 is used to restrict the maximum size of the gastric sac outlet 95, in addition to preventing the enlargement of the gastric sac outlet 95, and avoiding the food being too fast and thus the stomach The capsule outlet 95 passes through and prolongs the satiety time of the stomach 90, thereby achieving a longer lasting weight loss effect.

Further, as shown in FIG. 6 , the first clamping member 10 and the second clamping member 20 are separately disposed, and the hook members 30 can be made into several different sizes and lengths (as shown in FIG. 5 and FIG. 6, L1, L2), in order to meet the thickness requirements of different stomachs 90, using the appropriate size of the hook 30, the force of the first clamping member 10 and the second clamping member 20 applied to the stomach portion 90 can be effectively adjusted. The anterior stomach wall 91 and the posterior stomach wall 92 are closed in a state of no/low compression force, ensuring that the occluded portion maintains blood flow, and effectively prevents the stomach tissue from being necrotic due to excessive clamping. Moreover, the ridges 12 of the first clamping member 10 can also be made in different sizes (R1, R2 as shown in FIG. 5 and FIG. 6) to form different maximum sizes of the gastric capsule outlets 95. Furthermore, if it is necessary to ensure the fixing effect between the first clamping member 10 and the second clamping member 20 and the stomach portion 90, at least one surgical suture 50 can be sewn to the first clamping member 10 and the second clamping member. The hollow frame of the holding member 20 and the surface of the stomach portion 90 (as shown in Fig. 2) also require only a small amount of suturing action, which does not affect the operation time.

Compared with the traditional stomach compartment technology, this case has the following advantages:

1. In this case, compared with the previous case No. 091219707, the former case needs to be tied and bound by the open end of the fixture of the clamp, which is technically troublesome; and the first clamping member 10 and the second clamping member in the present case 20 simply fixes the hook 30 to the predetermined position of the stomach portion 90 to complete the positioning, eliminating the need for a fixing procedure for the wire wire to be tied, and the operation difficulty is reduced, and the operation time can be greatly shortened.

2. The first hook portion 31 and the second hook portion 32 of the present case are formed by bending the end portion of the hook member 30 to the inner side, so that the length between the first hook portion 31 and the second hook portion 32 is smaller than the length of the hook member 30. The opening 33, after the hook 30 is hooked with the first clamping member 10 and the second clamping member 20, the elastic force of the stomach portion 90 can make the first hook portion 31, the second hook portion 32 and the first hooking portion 11. The second hooking portion 21 is stably coupled and is not easily detached from the opening 33.

3. The first clamping member 10, the second clamping member 20 and the hook member 30 are separately disposed, and the hook members 30 can be made into several different sizes and lengths, so as to meet the thickness requirements of different stomach portions 90, The size of the suitable hook member 30 can effectively adjust the force applied by the first clamping member 10 and the second clamping member 20 to the stomach portion 90, so that the front stomach wall 91 and the posterior stomach wall 92 are in a state of no/low compression force. It is closed, ensuring that the clamping site maintains blood flow, so there is no damage to the stomach tissue.

4. The hollow frame-shaped first clamping member 10 and the second clamping member 20 enable the sandwiched stomach wall to maintain a relatively high blood circulation, thereby avoiding the situation of poor necrosis or degeneration of the gastric wall of the pinched stomach.

5. The detachable stomach clamp 1 of the present invention is fixed to the stomach portion 90 as needed, and the hollow frame-like design can be used for suturing and fixing the surgical suture 50 and the like on the stomach wall.

6. In this case, the stomach 90 is made into a physical compartment, and the detachable stomach clamp 1 can be removed from the stomach 90 in the future, without the disadvantage that the traditional destructive gastric compartment technique cannot restore the stomach 90 in the future.

7. In this case, compared with the technique of destructive gastric compartment, the detachable stomach clamp 1 and the laparoscopic instrument perform the gastric compartment technique, the operation time is short, the abdominal wound is small, the amount of bleeding is small, the pain is reduced, and the infection probability is reduced. There is no risk of surgical wound leakage.

From the above detailed description, it will be apparent to those skilled in the art that the present invention is indeed quite different from the conventional technology and has considerable novelty. Moreover, this creation has the unpredictable effects of conventional technology, and it has already met the positive requirements of patent approval, and has filed a patent application according to law.
