An inner foreskin support shield assembly for an anastomosis device

Abstract

This invention discloses a foreskin inner support shield assembly for a stapler, including an inner support shield and a shield connecting rod. The advantages of this invention are: it abandons the traditional single-size, fixed-size glans shield structure, adopting a flexible adjustment structure where the shield opening can be gradually adjusted from large to small. This not only provides better protection but also eliminates the hassle of selecting a large number of different glans shields. Furthermore, the adjusted inner support shield's inner wall leaves sufficient clearance for subsequent reasonable operations between itself and the glans. The inner support shield's surface is fitted with a thin rubber sleeve, and the surface of the rubber sleeve is moistened with cleaning fluid, improving patient comfort and speeding up the process for the foreskin. By guiding the cleaning fluid N+1 times to the contractile expansion filling part, the contractile expansion filling part pushes the foldable part inward again, reducing the pain caused by foreskin cutting and separation and rubbing against the inner support shield opening.

Description

Technical Field

[0001] This invention relates to the field of surgical instrument technology, specifically to a preputial support shield assembly for a stapler. Background Technology

[0002] A circumcision stapler is a medical device used in circumcision surgery. It uses titanium or stainless steel staples to replace traditional manual suturing, allowing for rapid cutting and suturing of the foreskin. During the procedure, the surgeon needs to insert the stapler's inner foreskin structure into the foreskin to cover and protect the glans penis. This inner foreskin structure is also known as a glans shield. However, existing glans shields have fixed dimensions, requiring various sizes, leading to cumbersome procedures and inconsistent compatibility, increasing the difficulty of the cutting and separation process. Therefore, this paper proposes a foreskin inner support shield assembly for a stapler to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide a foreskin inner support cover assembly for an anastomosis device in order to solve the above-mentioned problems.

[0004] The present invention achieves the above-mentioned objective through the following technical solution: a foreskin inner support cover assembly for an anastomosis device, comprising an inner support cover and a cover connecting rod. The opening of the inner support cover forms multiple pushable portions through a set of partition gaps. A shrinkable expansion filling portion is provided inside the annular groove on the surface of the inner support cover, and the shrinkable expansion filling portion forms an outward thrust on the resettable bending portion located at the bottom of each pushable portion by expansion. The same conduit is distributed inside the channel inside the inner support cover and inside the cover connecting rod. A rubber sleeve is fitted on the surface of the inner support cover, and one edge of the rubber sleeve is connected to the inner wall of the outwardly folded groove on the inner support cover.

[0005] In a further technical solution, the shrink-expansion filling part is composed of annular liquid-absorbing and expanding resin and annular tubing. The annular tubing is installed inside the annular liquid-absorbing and expanding resin, and the surface of the annular tubing has a number of micropores. The annular tubing is connected to the conduit.

[0006] In a further technical solution, one end of the conduit is connected to the output port of the filling part fitting.

[0007] In a further technical solution, the filling tube is composed of two interconnected short tubes, which are filled with cleaning fluid. The short tube in the vertical direction is connected to the second push-pull rod through a piston, and the short tube in the horizontal direction is connected to the first push-pull rod through another piston. Both the first push-pull rod and the second push-pull rod are fitted with return springs.

[0008] In a further technical solution, the outer end of the push-pull rod is connected to the screw-pull assembly, and the outer end of the push-pull rod is in contact with the firing assembly. The screw-pull assembly and the firing assembly are respectively located at the rear end and the front end of the tubular housing.

[0009] A further technical solution is to provide a cutting blade washer inside the outward-facing groove.

[0010] The beneficial effects of this invention are:

[0011] Abandoning the traditional single fixed-size glans cover structure, it adopts a flexible adjustment structure that allows the cover opening to be gradually adjusted from large to small. This not only better matches the implementation of protection, but also saves the trouble of having to choose a large number of different glans covers. Furthermore, the adjusted inner support cover has a gap space between the inner wall and the glans area for subsequent reasonable operation.

[0012] The inner support shield is fitted with a thin rubber sleeve, and the surface of the rubber sleeve is moistened with cleaning fluid, which improves patient comfort and speeds up the treatment of the foreskin area by medical staff.

[0013] By guiding the cleaning fluid N+1 times into the shrinking and expanding filling part, the shrinking and expanding filling part pushes the pushable part inward and closes again, reducing the pain caused by foreskin cutting and separation and the rubbing of the inner support shield opening.

[0025] Please see Figure 1-5 As shown, a foreskin inner support cover assembly for an anastomosis device includes an inner support cover 1 and a cover connecting rod 2. The opening of the inner support cover 1 forms multiple pushable portions 111 through a set of partition gaps 110. A shrinkable expansion filling portion 121 is provided inside the annular groove 120 on the surface of the inner support cover 1, and the shrinkable expansion filling portion 121 expands to generate an outward thrust on the resettable bending portion 122 located at the bottom of each pushable portion 111. The same conduit 3 is distributed inside the channel inside the inner support cover 1 and inside the cover connecting rod 2. A rubber sleeve 140 is fitted on the surface of the inner support cover 1, and one edge of the rubber sleeve 140 is connected to the inner wall of the outwardly turned groove 130 on the inner support cover 1.

[0026] The shrink-expansion filling part 121 is composed of annular liquid-absorbing and expanding resin and annular tubing. The annular tubing is installed inside the annular liquid-absorbing and expanding resin. The surface of the annular tubing has several micropores, and the annular tubing is connected to the conduit 3. One end of the conduit 3 is connected to the output port of the filling part fitting 4. The filling part fitting 4 is composed of two short tubes that are connected to each other. The two short tubes are filled with cleaning liquid. When the filling part fitting 4 is pushed and the cleaning liquid inside is discharged, the cleaning liquid can be guided into the annular tubing through the small inner diameter conduit 3. Then the cleaning liquid seeps into the annular liquid-absorbing and expanding resin from the micropores on the annular tubing. Each time, an equal amount of cleaning liquid is drawn into the annular liquid-absorbing and expanding resin, so that the annular liquid-absorbing and expanding resin expands to different degrees.

[0027] Combination Figure 5 As shown, the inside of the short tube in the vertical direction is connected to the second push-pull rod 412 via a piston component, and the inside of the short tube in the horizontal direction is connected to the first push-pull rod 411 via another piston component. Both the first push-pull rod 411 and the second push-pull rod are fitted with return springs 413. The outer end of the first push-pull rod 411 is connected to the screw-pull assembly 6, and the outer end of the second push-pull rod 412 is in contact with the firing assembly 5. The screw-pull assembly 6 and the firing assembly 5 are respectively located at the rear end and the front end of the tubular housing 7.

[0028] The screw-pull assembly 6 consists of an end cap and a rod located inside the tubular housing 7. The screw hole structure on the end cap is threadedly connected to the rear end port of the tubular housing 7, so as to achieve the effect of moving back and forth by screwing. The end of the rod and the end of the push-pull rod 411 are rotatably connected to each other.

[0029] The back of the firing handle in the trigger assembly 5 is gradually brought closer to the outer end of the push-pull rod 412 by gripping and pressing until the two come into contact and are pressed together. This pressing is performed at the moment the foreskin cutting operation is completed.

[0030] The outer groove 130 is provided with a cutting blade washer 150. The cutting blade washer 150 is available in various specifications. The cutting blade washer 150 is installed after the inner support cover 1 is adjusted.

[0031] Working principle: Based on the measurement of the patient's glans penis by medical staff, each press of the push-pull lever 411 releases a measured amount of cleaning fluid from the filling part tube 4 through the catheter 3 into the contraction-expansion filling part 121. This causes the contraction-expansion filling part 121 to complete one fluid absorption and expansion, creating an outward expansion force. This outward expansion force pushes a set of pushable parts 111 inward to a closed state, adjusting the size of the inner support cover 1. Medical staff then compare the opening of the inner support cover 1 with the measured hole on the measuring tool. If the sizes match, the inner support cover 1 can be used to cover the patient's glans penis, and the foreskin area... Wrapped on the surface of the inner support shield 1; if the adjusted shield opening size is still larger than the measured size of the patient's glans, press the push-pull rod 411 again (or N times) to allow a certain amount of cleaning fluid to enter the shrink-expansion filling part 121 from the filling part tube 4 through the catheter 3, so that the shrink-expansion filling part 121 completes secondary fluid absorption and expansion until the size matches. The advantage of this is that it abandons the traditional single fixed size glans shield structure and adopts a flexible adjustment structure that can gradually adjust the shield opening from large to small. This can not only better match the implementation of protection, but also save the trouble of selecting a large number of different glans shields. In addition, there is a gap space between the inner wall of the adjusted inner support shield 1 and the glans area for subsequent reasonable operation.

[0032] The inner support shield 1 is fitted with a thin rubber sleeve 140. The surface of the thin rubber sleeve 140 is moistened with cleaning fluid to improve patient comfort and speed up the treatment of the foreskin area by medical staff.

[0033] When the size of the inner support shield 1 is matched and adjusted, the medical staff installs the cutting blade washer 150 in the eversion groove 130 on the inner support shield 1, and then inserts the inner support shield 1 into the foreskin. At the same time, the inner support shield 1 fits snugly over the glans. When the foreskin is cut instantly using the stapler, the back of the firing handle in the firing assembly 5 touches the outer end of the push-pull rod 412 and presses it, which can complete the N+1 times of guiding the cleaning fluid to the shrinking and expanding filling part 121, so that the shrinking and expanding filling part 121 pushes the pushable part 111 inward and closes, reducing the pain caused by the foreskin cutting and separation and the scratching of the inner support shield 1 opening.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
