Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an intestinal anastomosis device that is easy to fix. Background Technology

[0002] A stapler is a surgical suture device used in medicine to replace traditional manual suturing. Due to the development of modern technology and the improvement of manufacturing techniques, its main working principle is to use titanium staples to cut or anastomose tissue, similar to the structure of a stapler. Depending on the application, staplers can be mainly divided into skin staplers, digestive tract (esophagus, stomach and intestines) circular staplers, rectal staplers, vascular staplers, lung cutting staplers, etc. Staplers are generally convenient to use, tight and appropriately tight, and especially have the advantages of fast suturing, simple operation and few side effects and surgical complications, so they have been increasingly widely used.

[0003] The main component of a traditional intestinal anastomosis device is a biodegradable intestinal anastomosis stent. The general installation process is as follows: After the surgeon removes the diseased part of the intestine, the two ends of the intestine are placed on the middle of the biodegradable intestinal anastomosis stent and sutured. After a period of time, the biodegradable intestinal anastomosis stent begins to gradually disintegrate, and the clinical results are as expected. When using the biodegradable intestinal anastomosis stent, the first assistant needs to use a special round clamp to fix and hold the biodegradable intestinal anastomosis stent to facilitate the surgeon's suturing. Due to the long operation time, the round clamp may loosen. At the same time, due to the physiological characteristics of the two ends of the intestine, they may twist when placed on the middle of the biodegradable intestinal anastomosis stent. Therefore, the first or second assistant needs to use surgical forceps to adjust the position of the two ends of the intestine. Multiple people need to work together to complete the final intestinal anastomosis. The suturing speed is relatively slow. Therefore, an intestinal anastomosis device that is easy to fix is ​​proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the fixation method of intestinal anastomosis device in the prior art is inconvenient and slow, and to propose an intestinal anastomosis device that is easy to fix.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An easy-to-fix intestinal anastomosis device includes a biodegradable intestinal anastomosis stent, with a fixing component on the upper part of the biodegradable intestinal anastomosis stent for quickly fixing its own position, and two adjusting components in the middle part of the fixing component for adjusting the intestinal setting angle.

[0007] The fixing component includes a fixing rod, a fixing ring fixedly disposed in the middle of the fixing rod, a support rod fixedly disposed in the middle of the lower end of the fixing ring, and two arc-shaped clamping blocks for fixing and holding the biodegradable intestinal anastomosis stent at the lower end of the support rod.

[0008] The above technical solution further includes:

[0010] The lower end of the support rod is symmetrically equipped with two rotating shafts, and an arc-shaped clamping block is fixed in the middle of the rotating shaft. A driving block is fixed in the middle of the outer side of the arc-shaped clamping block. The lower end of the rotating rod is hinged to the middle of the driving block on the same side. Multiple limiting strips are fixed in the middle of the biodegradable intestinal anastomosis stent. Multiple arc-shaped limiting grooves that cooperate with the limiting strips are opened on the inner side of the arc-shaped clamping block.

[0011] The above technical solution further includes:

[0012] The adjusting assembly includes a sliding ring slidably disposed in the middle of the fixed rod, a fixed block fixedly disposed on one side of the middle of the sliding ring, the fixed block being fixedly connected to the fixed rod by a locking bolt, and an adjusting bolt being threadedly connected to the middle of the upper end of the sliding ring;

[0013] An adjusting block is fixedly provided at the lower middle part of the sliding ring. A rectangular sliding cavity is opened inside the adjusting block, and an adjusting rod is slidably provided inside the rectangular sliding cavity. A rectangular limiting plate is fixedly provided at the middle part of the adjusting rod, and a compression spring is sleeved below the middle part of the adjusting rod. The upper end face of the compression spring abuts against the lower end face of the rectangular limiting plate, and the lower end face of the compression spring abuts against the bottom of the rectangular sliding cavity.

[0014] The fixed rod has a rectangular groove in the middle to facilitate the sliding of the adjusting bolt and the adjusting rod. A pressure plate is fixedly installed at the upper end of the adjusting rod inside the fixed rod. The lower end of the adjusting bolt abuts against the upper end surface of the pressure plate.

[0015] The above technical solution further includes:

[0016] A housing is fixedly provided at the lower end of the adjusting rod and below the adjusting block. Two arc-shaped mounting blocks are symmetrically fixed at the lower end of the housing. An arc-shaped adjusting ring is slidably provided between the two arc-shaped mounting blocks. A worm gear is rotatably provided inside the housing. Multiple adjusting tooth blocks that cooperate with the worm gear are fixedly provided at the upper end of the arc-shaped adjusting ring. Multiple sets of conical adjusting pins are fixedly provided on the inner side of the arc-shaped adjusting ring.

[0017] The above technical solution further includes:

[0018] The arc-shaped mounting block has a T-shaped cross-section, and the arc-shaped adjusting ring has two symmetrical arc-shaped sliding grooves in the middle that are used in conjunction with the arc-shaped mounting block.

[0019] The above technical solution further includes:

[0020] The cross-section of the arc-shaped adjusting ring is a fan ring, and the central angle of the fan ring is 180°.

[0021] The above technical solution further includes:

[0022] The support rod has a placement groove in the middle for placing a positioning pin, and a limiting groove in the middle for facilitating the sliding of the hinge seat.

[0023] The above technical solution further includes:

[0025] The above technical solution further includes:

[0026] The number of limiting strips is ten, and they are evenly distributed in a vertical plane. The length of each limiting strip is greater than the width of the arc-shaped clamping block.

[0027] The above technical solution further includes:

[0028] The radius of the arc-shaped adjusting ring is larger than the radius of the arc-shaped clamping block.

[0029] The above technical solution further includes:

[0030] The middle part of the fixed rod is fixed with an operating block that is easy to hold, and the cross-section of the operating block is U-shaped.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] In this invention, the biodegradable intestinal anastomosis stent can be directly and quickly fixed and clamped by the fixing component. The interaction between the two arc-shaped clamping blocks and the limiting strip set on the surface of the biodegradable intestinal anastomosis stent can prevent the biodegradable intestinal anastomosis stent from twisting after being fixed and clamped. Moreover, the positioning pin limits the sliding block, so that the biodegradable intestinal anastomosis stent does not need to be squeezed by the user again after being clamped, which greatly reduces the physical exertion of the user. In addition, the arc length of the two arc-shaped clamping blocks is short, and the opening method is simple and quick. The biodegradable intestinal anastomosis stent can be easily clamped or released without hindering the suturing of the two ends of the intestine.

[0033] In this invention, two adjusting components are slidably installed in the middle of the fixed rod. This not only allows the overall position of the adjusting components to be changed according to the actual length of the intestine, but also allows for selection of a suitable adjusting position based on the actual tortuosity of the intestine, thereby improving the adjustment effect on both ends of the intestine. The relative distance between the arc-shaped adjusting ring and the outer surface of the biodegradable intestinal anastomosis stent can be adjusted by the interaction of the adjusting bolt, adjusting rod, and housing, thereby adjusting the vertical compression force on both ends of the intestine. Simultaneously, the interaction between the worm gear and the adjusting tooth block located in the middle of the outer side of the arc-shaped adjusting ring effectively corrects intestinal deviation, thereby changing the setting angle of both ends of the intestine in the middle of the biodegradable intestinal anastomosis stent, improving the quality of intestinal suturing. Furthermore, the entire adjustment process does not require the participation of a first or second assistant; the surgeon can adjust it independently according to the actual situation. This not only reduces the number of people involved in intestinal anastomosis but also speeds up the suturing time and improves the suturing quality, solving the problem of traditional intestinal anastomosis requiring multiple participants.

[0054] Furthermore, the adjusting component 3 includes a sliding ring 301 slidably disposed in the middle of the fixed rod 201, a fixed block 302 fixedly disposed on one side of the middle of the sliding ring 301, the fixed block 302 being fixedly connected to the fixed rod 201 by a locking bolt, and an adjusting bolt 303 being threadedly connected to the middle of the upper end of the sliding ring 301.

[0055] An adjusting block 304 is fixedly provided at the lower middle part of the sliding ring 301. A rectangular sliding cavity is provided inside the adjusting block 304, and an adjusting rod 305 is slidably provided inside the rectangular sliding cavity. A rectangular limiting plate 306 is fixedly provided at the middle part of the adjusting rod 305. A compression spring 307 is also sleeved below the middle part of the adjusting rod 305. The upper end face of the compression spring 307 abuts against the lower end face of the rectangular limiting plate 306, and the lower end face of the compression spring 307 abuts against the bottom of the rectangular sliding cavity.

[0056] The middle part of the fixed rod 201 has a rectangular groove to facilitate the sliding of the adjusting bolt 303 and the adjusting rod 305. The upper end of the adjusting rod 305 and the inside of the fixed rod 201 are fixedly provided with a pressure plate 3051. The lower end of the adjusting bolt 303 abuts against the upper end surface of the pressure plate 3051.

[0057] Furthermore, a housing 308 is fixedly provided at the lower end of the adjusting rod 305 and below the adjusting block 304. Two arc-shaped mounting blocks 309 are symmetrically fixed at the lower end of the housing 308. An arc-shaped adjusting ring 310 is slidably provided between the two arc-shaped mounting blocks 309. A worm gear 311 is rotatably provided inside the housing 308. Multiple adjusting teeth blocks that cooperate with the worm gear 311 are fixedly provided at the upper end of the arc-shaped adjusting ring 310. Multiple sets of conical adjusting pins are fixedly provided on the inner side of the arc-shaped adjusting ring 310.

[0058] Furthermore, the cross-section of the arc-shaped mounting block 309 is T-shaped, and the center of the arc-shaped adjusting ring 310 is symmetrically provided with two arc-shaped sliding grooves that cooperate with the arc-shaped mounting block 309.

[0059] Furthermore, the cross-section of the arc-shaped adjusting ring 310 is a fan ring, and the central angle of the fan ring is 180°.

[0060] Furthermore, the middle part of the support rod 203 is provided with a placement groove for the positioning pin 206, and the middle part of the support rod 203 is also provided with a limiting groove to facilitate the sliding of the hinge seat 207.

[0061] Furthermore, the lower end of the support rod 203 is provided with a rotating cavity to facilitate the rotation of the two arc-shaped clamping blocks 209.

[0062] Furthermore, there are ten limiting strips 101, which are evenly distributed in the vertical plane, and the length of the limiting strips 101 is greater than the width of the arc-shaped clamping block 209.

[0063] Furthermore, the radius of the arc-shaped adjusting ring 310 is larger than the radius of the arc-shaped clamping block 209.

[0064] Furthermore, an operating block for easy gripping is fixedly provided in the middle of the fixed rod 201, and the cross-section of the operating block is U-shaped.

[0065] As described above, after the surgeon has removed the intestinal lesion and taken out the biodegradable intestinal anastomosis stent 1, the assistant pulls out the positioning pin 206 in the fixation component 2, thereby releasing the restriction on the sliding block 204. Then, the support rod 203 is moved to directly above the biodegradable intestinal anastomosis stent 1, that is, the two arc-shaped clamping blocks 209 are in an open position and directly above the biodegradable intestinal anastomosis stent 1. The sliding block 204 is pressed down, and the sliding block 204 moves downward, causing the two hinge seats 207 to move downward, that is, driving the two rotating rods 208 to rotate downward at a certain angle. Since the lower end of the rotating rod 208 is hinged to the middle of the driving block 210 on the same side, it can drive the driving block 210 to rotate downward, thereby causing the arc-shaped clamping blocks 209 to rotate about the center line of the rotation axis. Finally, the two arc-shaped clamping blocks 209 clamp and fix the biodegradable intestinal anastomosis stent 1. It is worth noting that it is essential to ensure that the limiting strip 101 in the middle of the biodegradable intestinal anastomosis stent 1 is partially engaged in the arc-shaped sliding groove inside the arc-shaped clamping block 209. This arrangement not only reduces the arc length of the arc-shaped clamping block 209 and minimizes its interference with intestinal suturing, but also effectively prevents the biodegradable intestinal anastomosis stent 1 from rotating during clamping, as the limiting strip 101 is engaged in the arc-shaped sliding groove. After the two arc-shaped clamping blocks 209 have clamped and fixed the biodegradable intestinal anastomosis stent 1, the operator inserts the positioning pin 206 into the middle of the sliding block 204 and into the positioning hole to limit the sliding block 204. At this point, the biodegradable intestinal anastomosis stent 1 can be clamped and fixed without any external force. The operator only needs to hold the operating block to fix the biodegradable intestinal anastomosis stent 1, making the operation simple and convenient.

[0066] Example 2: This example is basically the same as the previous example, except that the adjusting component 3 includes a sliding ring 301 that is slidably disposed in the middle of the fixed rod 201, a fixed block 302 that is fixedly disposed on one side of the middle of the sliding ring 301, the fixed block 302 being fixedly connected to the fixed rod 201 by a locking bolt, and an adjusting bolt 303 being threadedly connected to the middle of the upper end of the sliding ring 301.

[0067] An adjusting block 304 is fixedly provided at the lower middle part of the sliding ring 301. A rectangular sliding cavity is provided inside the adjusting block 304, and an adjusting rod 305 is slidably provided inside the rectangular sliding cavity. A rectangular limiting plate 306 is fixedly provided at the middle part of the adjusting rod 305. A compression spring 307 is also sleeved below the middle part of the adjusting rod 305. The upper end face of the compression spring 307 abuts against the lower end face of the rectangular limiting plate 306, and the lower end face of the compression spring 307 abuts against the bottom of the rectangular sliding cavity.

[0068] The middle part of the fixed rod 201 has a rectangular groove to facilitate the sliding of the adjusting bolt 303 and the adjusting rod 305. The upper end of the adjusting rod 305 and the inside of the fixed rod 201 are fixedly provided with a pressure plate 3051. The lower end of the adjusting bolt 303 abuts against the upper end surface of the pressure plate 3051.

[0069] Furthermore, a housing 308 is fixedly provided at the lower end of the adjusting rod 305 and below the adjusting block 304. Two arc-shaped mounting blocks 309 are symmetrically fixed at the lower end of the housing 308. An arc-shaped adjusting ring 310 is slidably provided between the two arc-shaped mounting blocks 309. A worm gear 311 is rotatably provided inside the housing 308. Multiple adjusting teeth blocks that cooperate with the worm gear 311 are fixedly provided at the upper end of the arc-shaped adjusting ring 310. Multiple sets of conical adjusting pins are fixedly provided on the inner side of the arc-shaped adjusting ring 310.

[0070] As can be seen from the above, after the biodegradable intestinal anastomosis stent 1 is fixed, the surgeon places both ends of the intestine onto the middle of the biodegradable intestinal anastomosis stent 1. Due to its physiological characteristics, twisting may occur when placed onto the middle of the biodegradable intestinal anastomosis stent. Therefore, the adjusting component 3 needs to be adjusted to adjust both ends of the intestine. First, the overall setting position of the adjusting component 3 is adjusted according to the actual twisting part of the intestine. Then, the fixing block 302 is fixedly connected to the fixing rod 201 by the locking bolt, thus fixing the setting position of the adjusting component 3. Then, the operator turns the adjusting bolt 303. After the adjusting bolt 303 is turned, it will spiral down. Since the lower end of the adjusting bolt 303 abuts against the upper end face of the pressure plate 3051, the adjusting rod 305 moves downward. The downward movement of the adjusting rod 305 further... The worm gear 308 is driven to move downwards, and the arc-shaped adjustment ring 310 located below the worm gear 308 also moves downwards. The arc-shaped adjustment ring 310 compresses the intestine. Multiple sets of conical adjustment rings located inside the arc-shaped adjustment ring 310 limit the movement of the intestine. When the operator turns the worm gear 311, the worm gear 311 can drive the arc-shaped adjustment ring 310 to rotate in the horizontal plane, thereby rotating the end of the intestine and correcting the angle of the intestine, which facilitates subsequent suturing. In this process, no other personnel are required to operate. Only the surgeon needs to adjust the rotation of the worm gear 311 according to the actual situation on site. It is convenient and quick. Moreover, the surgeon can operate alone without communicating with the first or second assistant, and the adjustment effect is better, thus speeding up the suturing speed.
