Description

Technical Field

[0001] The present invention relates to the field of medical auxiliary equipment, and in particular to an auxiliary supporting device for an intestinal stapler and an operating method thereof. Background Art

[0002] Staplers are medical devices that replace traditional manual suturing. Due to the development of modern science and technology and the improvement of manufacturing technology, the staplers currently used in clinical practice are reliable in quality, easy to use, tight, and of appropriate tightness. They are particularly fast in suturing, simple in operation, and have few side effects and surgical complications. They also enable lesion removal in tumors that were previously unresectable, and are very popular and highly praised by clinical surgeons at home and abroad. However, during the use of existing staplers, the intestinal entrance is not open, so the stapler cannot enter the intestine smoothly. The stapler and the intestine are usually tied and fixed with a rubber band, which is easy to slide outside the stapler, and the surrounding intestinal tissue may be accidentally clamped, which increases the difficulty of cutting and anastomosis. It is difficult to complete the suturing operation by one person, which is not conducive to improving the firmness of surgical suturing.

[0003] After searching, the Chinese patent with application number 202120124798.6 discloses an anorectal stapler that is convenient for supporting the intestine, including a grip and a support mechanism, a main body is fixed on the top of the grip, and a gun barrel is snap-connected to the main body, and a suture gun head is fixed on the gun barrel, a sleeve is slidably connected to the gun barrel, the bolt passes through the inner wall of the sleeve and contacts the gun barrel, the fixing ring is fixed to the left side of the sleeve, and the two ends of the fixing ring are rotatably connected to the connecting rod, and the two ends of the connecting rod are respectively fixed with a support rod and a gear, and the gear is meshed with the rack. The anorectal stapler that is convenient for supporting the intestine is provided with a gear and a rack, and the gear meshed with it can be driven to rotate by sliding the rack, and the rotation of the gear drives the connecting rod and the support rod to support outward at the same time, so that the intestine outside the intestinal wound can be supported when the intestine is sutured, so that the doctor can more conveniently observe the suture of the wound, thereby reducing the operation time and reducing the risk of surgery.

[0004] The anorectal stapler in the above-mentioned prior art requires manual rotation of the threaded sleeve during the wound suturing process so that the support rod at the head end of the stapler can support the intestine. During the anastomosis operation, both hands are required and the operation process is relatively time-consuming. In addition, there is a lack of an intestinal expansion device during the stapler entry process, making it difficult for the stapler to enter the intestinal tract. Summary of the invention

[0005] The above-mentioned prior art solves the technical problems that the stapler lacks intestinal support and expansion during its entry into the intestine, making it difficult to enter the intestine, and that manual operation is required to support the outer intestine during the stapler suturing process, making the operation more cumbersome and time-consuming.

[0006] Technical idea: Starting from the problems of the prior art, this application provides an auxiliary support device for an intestinal stapler. During the process of the stapler entering the intestine, the support plate is driven by the engagement of the rack and pinion to expand the intestine, which facilitates the stapler to enter the intestine. During the stapler suturing process, the airbag is inflated to fix the intestine to be sutured and the stapler, and other intestines are isolated, thereby providing dual guarantees of fixation and isolation for the stapler to enter the intestine and during the suturing process.

[0007] To achieve the above object, the technical solution adopted by the present invention is: The present application provides an auxiliary support device for an intestinal stapler, comprising a stapler body, the head end of the stapler body being provided with a spreading component for spreading the intestine, and the tail end of the stapler body being connected with an auxiliary clamping component, the auxiliary clamping component extending between a first section of the intestinal tube and a second section of the intestinal tube; The expansion component and the auxiliary clamping component cooperate with each other to achieve clamping and fixation between the first section of the intestinal tube, the second section of the intestinal tube and the anastomosis device body, and to isolate other intestinal tubes.

[0008] It should be noted that the stapler body is of prior art, including a stapler seat and a control handle.

[0009] Furthermore, the expansion assembly includes a support ring, a rack, a gear, a motor, an adjustment frame, a gear plate and a support plate; A support ring is provided on the outer sleeve of the stapler body, and a plurality of racks are slidably connected to the support ring at intervals; one end of the rack is slidably connected to the stapler body, and the other end is fixedly connected to the support plate; an adjustment frame is provided on the inner side of the support plate, and a slide groove is provided on the adjustment frame, a toothed disc is rotatably connected in the slide groove, and a plurality of gears are rotatably connected in the adjustment frame; each of the gears is meshed with the rack and the toothed disc, and a motor is connected to the end of one of the gears.

[0010] In detail, the support plate is an arc-shaped structure, and the gear is rotatably connected to the adjustment frame through a connecting rod.

[0011] Furthermore, the auxiliary clamping assembly includes a fixing ring, an air pump, an inflation tube and an air bag; The fixing ring is sleeved on the rear end of the stapler body, and both sides of the fixing ring are connected to air pumps; each air pump is connected to an inflation tube, and the end of the inflation tube is connected to the air bag.

[0012] Specifically, electric telescopic rods are symmetrically arranged on the inner side of the airbag, and an arc-shaped clamping plate is connected to the end of each electric telescopic rod.

[0013] It should be noted that the airbag forms an annular ring structure.

[0014] In the above technical solution, a method for operating an auxiliary support device for an intestinal stapler comprises the following steps: S1: Place the stapler head into the intestine; S2: By adjusting the expansion component to expand the intestine, the stapler body is assisted to enter the intestine as a whole; S3: By inflating air into the auxiliary clamping component, the inner side of the auxiliary clamping component clamps the intestine and the outer side isolates other intestines.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention achieves the effect of expanding the intestine by setting a spreading component at the head end of the stapler body, which facilitates the stapler body to enter the intestine; one of the gears is driven to rotate by a motor, and the gear is engaged with the rack and the toothed disc, so that the gear drives the rack to move outward, and the rotation of the toothed disc drives the other gears to rotate synchronously, and the movement of the rack drives the support plate to move outward, and the expansion and spreading effect of the intestinal wall is achieved through the support plate, which facilitates the stapler to enter the intestinal tract.

[0016] 2. In the present invention, after the stapler body enters the intestine, the motor reverses, and then through the cooperation of the gear, rack and toothed disc, the rack drives the support plate to reset, and the cooperation between the support plate and the arc-shaped clamping plate forms a clamping fixation between the stapler body and the first and second intestinal sections.

[0028] During the specific operation, the anvil of the stapler body 1 is inserted into the first section of the intestinal tube 4 , and the anvil is connected to the head end of the stapler body 1 .

[0029] Further, by starting the motor 24, one of the gears 23 is driven to rotate by the motor 24, and the gear 23 is meshed with the rack 22 and the toothed disc 26, so that the gear 23 drives the rack 22 to move outward, and the toothed disc 26 rotates to drive the other gears 23 to rotate synchronously. The movement of the rack 22 drives the support plate 27 to move outward, and the support plate 27 realizes the effect of expanding the intestinal wall. Embodiment 2

[0030] Based on Example 1, refer to Figure 7 As shown, in order to better assist the stapler body 1 in clamping and anastomosing the first and second intestinal tube sections 4 and 5 , an auxiliary clamping assembly 3 is provided at the tail end of the stapler body 1 , and the clamping assembly 3 extends between the first and second intestinal tube sections 4 and 5 .

[0031] In detail, the expansion component 2 and the auxiliary clamping component 3 cooperate with each other to achieve the clamping and fixation between the first section of the intestinal tube 4, the second section of the intestinal tube 5 and the anastomosis device body 1, and to isolate other intestinal tubes.

[0032] Specifically, the auxiliary clamping assembly 3 includes a fixing ring 31, an air pump 32, an inflation tube 33 and an air bag 34; The fixing ring 31 is sleeved on the rear end of the stapler body 1 , and both sides of the fixing ring 31 are connected to air pumps 32 ; each of the air pumps 32 is connected to an inflation tube 33 , and the end of the inflation tube 33 is connected to an air bag 34 .

[0033] As an example, electric telescopic rods 35 are symmetrically arranged on the inner side of the airbag 34 , and an arc-shaped clamping plate 36 is connected to the end of each electric telescopic rod 35 .

[0034] In particular, the arc-shaped splint 36 is made of a hard material, and will not cause the problem of adhesion and fusion with the intestine during the intestinal anastomosis process.

[0035] During the anastomosis between the first section of the intestinal tube 4 and the second section of the intestinal tube 5 by the stapler body 1, the air pump 32 is used to inflate the airbag 34 to expand the airbag 34, and the electric telescopic rod 35 is adjusted to make the arc splint 36 fit the first section of the intestinal tube 4 and the second section of the intestinal tube 5. The inner side of the arc splint 36 clamps and fixes the first section of the intestinal tube 4, the second section of the intestinal tube 5 and the stapler body 1 during the anastomosis, and the outer airbag 34 isolates other intestinal tubes.

[0036] Specific application cases: The intestinal stapler is a commonly used medical device in intestinal surgery. It can eliminate the tedious suturing process during the operation, making the intestinal anastomosis operation simple, time-saving and safe, and reducing complications such as anastomotic fistula.

[0037] The circular stapler can form two rings of staples and cut off the tissue inside the ring at the same time. It is often used for end-to-end or end-to-side anastomosis of internal organs. The handle of the stapler is designed to be straight or curved, and the anvil in front of it can also be detachable or tiltable to suit different tissues and organs, especially for different situations such as resection and anastomosis of the low rectum, cutting off the esophagus or transabdominal esophagojejunostomy. According to the different anastomosis diameters, it is divided into different specifications, suitable for anastomosis of intestinal lumens with different diameters of 21-33mm.

[0038] Compared with manual anastomosis, the advantages of staplers are safety, less chance of contamination, less trauma, and less leakage of intestinal contents. In addition, in some anastomosis (such as the anastomosis of the terminal rectum and colon), the use of staplers makes some operations that are difficult to complete with traditional manual sutures simpler, faster, and more reliable.

[0039] In order to facilitate the stapler to enter the intestine during surgery and to clamp and fix the stapler, the present application provides an auxiliary support device for the stapler based on the stapler.

[0040] During the specific operation, the anvil of the stapler body 1 is inserted into the first section of the intestinal tube 4 , and the anvil is connected to the head end of the stapler body 1 .

[0041] Further, by starting the motor 24, one of the gears 23 is driven to rotate by the motor 24, and the gear 23 is meshed with the rack 22 and the toothed disc 26, so that the gear 23 drives the rack 22 to move outward, and the toothed disc 26 rotates to drive the other gears 23 to rotate synchronously. The movement of the rack 22 drives the support plate 27 to move outward, and the support plate 27 realizes the effect of expanding the intestinal wall.

[0042] During the anastomosis between the first section of the intestinal tube 4 and the second section of the intestinal tube 5 by the stapler body 1, the air pump 32 is used to inflate the airbag 34 to expand the airbag 34, and the electric telescopic rod 35 is adjusted to make the arc splint 36 fit the first section of the intestinal tube 4 and the second section of the intestinal tube 5. The inner side of the arc splint 36 clamps and fixes the first section of the intestinal tube 4, the second section of the intestinal tube 5 and the stapler body 1 during the anastomosis, and the outer airbag 34 isolates other intestinal tubes.

[0043] The first section of the intestinal tube 4 and the second section of the intestinal tube 5 are connected and anastomosed by operating the control handle at the rear end of the stapler body 1. After the anastomosis operation is completed, the gas in the airbag 34 is emptied, and the stapler body 1 can be removed from the intestinal tube as a whole.

[0044] It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The protection scope required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
