Description

Technical Field

[0001] This invention belongs to the field of urological surgery technology, specifically relating to a circumcision device for urological surgery. Background Technology

[0002] The Department of Urology is a hospital department that primarily diagnoses and treats diseases of the "surgical" part of the urinary system. It mainly treats various urological diseases. The organs covered by urology include the kidneys, ureters, bladder, urethra, as well as the testes, epididymis, vas deferens, seminal vesicles, prostate, scrotum, penis, and foreskin of the male reproductive system. The foreskin, also known as the penile foreskin, is a double-layered, free, ring-shaped fold of skin in front of the penile neck that surrounds the glans penis. In adulthood, if the foreskin can be retracted but cannot expose the entire glans penis, it is called phimosis. Men with this condition can choose to undergo circumcision. Circumcision often uses a circumcision stapler.

[0003] In the prior art, application number 201910454287.8 discloses a circumcision anastomosis device for urology, which "uses a fixed component to fix it to the rear end of the foreskin to be circumcised. When the glans seat component is fixed in place and placed in the outer shell by the fixing nut, the outer shell moves outward towards the patient's penis and covers the front part of the penis. At this time, the adjusting outer ring is slightly rotated counterclockwise, the arc surface of the arc support block moves along the arc of the arc cavity, and the telescopic rod extends accordingly, and the telescopic rod and the arc support block are connected." As the angle increases, the angle between the arc-shaped support block and the arc-shaped fixing plate also changes due to the contact angle between the arc-shaped fixing plate and the foreskin. This fixes the foreskin between the area to be circumcised and the area not to be circumcised, preventing accidental movement of the foreskin during circumcision and facilitating subsequent hemostasis. It also reduces local bleeding and eliminates the need for pressure bandaging. It can effectively prevent accidental movement of the foreskin during circumcision, making the circumcision area relatively flat. However, when suturing is required after circumcision, this foreskin anastomosis circumcision device cannot hold the foreskin, making it difficult to suture the foreskin. Summary of the Invention

[0004] The purpose of this invention is to provide a circumcision device for urology to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a circumcision device for urology, comprising a top tube, a tail tube installed on one side of the top tube, a cutting blade located outside the cavity of the top tube, and a hemispherical stop block located inside the cavity of the top tube, characterized in that: the top tube and the tail tube are both hollow structures, an annular guide block is fixedly sleeved on the outer wall of the top tube, a limiting slider is slidably installed in the guide block, a telescopic rod is installed on one side of the limiting slider, a blade retainer is fixedly installed at the telescopic end of the telescopic rod, the cutting blade is sleeved in the groove of the blade retainer, and the tip of the cutting blade points towards the top tube;

[0006] The outer wall of the tail tube is fitted with two first fixing seats that are symmetrical about the tail tube. The side wall of the tail tube has two slots that are symmetrical about the center of the tail tube. The two slots are close to one of the first fixing seats and are located on the side of the two first fixing seats away from the top tube.

[0007] In one embodiment, a through hole is provided on the side wall of the top cylinder, which extends through both sides of the top cylinder, and a limit rod is slidably installed on the top cylinder through the through hole;

[0008] Four limiting posts arranged in a rectangular array are installed on the side of the top cylinder away from the tail cylinder. Each of the limiting posts is equipped with a limiting block. A support block is provided on the side of the top cylinder away from the tail cylinder. Four limiting holes are opened on the side of the support block near the top cylinder. Each of the limiting posts is inserted into one of the limiting holes on the support block.

[0009] The aforementioned support block is provided with a rotation limiting hole, and the end of the aforementioned limiting rod away from the top cylinder is slidably inserted into the rotation limiting hole of the support block. A constraint block is installed on the side of the aforementioned support block away from the top cylinder.

[0010] In one embodiment, a rotating handle is rotatably mounted on each of the first fixed seats on the tail tube, and a second fixed seat is mounted on the inner arc of each rotating handle. The two second fixed seats are symmetrical about the tail tube, and a connecting buckle is rotatably mounted on each of the second fixed seats of the rotating handle.

[0011] In one embodiment, a sliding member is slidably installed inside the tail cylinder cavity, and a baffle for locking the top cylinder is installed on the side wall of the sliding member away from the tail cylinder. The hemispherical block is installed at the end of the sliding member away from the tail cylinder and is slidably sleeved on the inner wall of the top cylinder.

[0012] In one embodiment, two springs symmetrical about the slider are installed on the side wall of the slider. The ends of the two springs away from the slider are connected to rubber pads, and top rods that penetrate the side wall of the slider are fixedly sleeved on the two rubber pads.

[0013] In one embodiment, the slider is a hollow structure, and an elliptical rotating block is fitted inside the slider cavity. The shapes of the two push rods match the shape of the elliptical rotating block.

[0014] In one embodiment, a connecting rod is fixed to one side of the elliptical rotating block, and two limiting strips symmetrical about the connecting rod are installed on the side wall of the connecting rod away from the elliptical rotating block.

[0015] In one embodiment, a tail stop is installed on the side of the tail tube away from the top tube.

[0016] In one embodiment, the tail tube is rotatably mounted with a sleeve rod via a tail stop, and a rotating handle is fixed to the end of the sleeve rod away from the tail tube.

[0017] In one embodiment, the side of the sleeve near the connecting rod is hollow, and the shape of the hollow structure of the sleeve matches the shape of the connecting rod and the two limiting strips.

[0018] The technical effects and advantages of this urological circumcision device:

[0019] When using this urological circumcision stapler during circumcision, after adjusting the position of the glans penis using the two rotating handles, the foreskin is moved from the restraint block along the support block to the top tube. The support block is then fitted onto the outer wall of the top tube, and a limiting collar is placed on the foreskin outside the support block. This structure can limit the foreskin during cutting. After cutting with the cutting blade, the limiting rod is rotated from the groove of the rotating limiting hole. After pulling out the limiting rod, the main structure of the circumcision stapler can be removed. At this time, the support block and the limiting collar still act on the foreskin after circumcision. This structure can still limit the foreskin at the circumcision site when removing the circumcision stapler after circumcision, so that the foreskin will not wobble due to lack of limiting after circumcision, resulting in a messy position of the foreskin after circumcision. This improves the limiting effect during suturing after circumcision.

[0020] During the fixation process of this urological circumcision device, pressing the two rotating handles at the position of the glans moves the sliding component towards the glans. After the sliding component moves, the hemispherical stop block abuts against the glans. At this time, rotating the rotating handle drives the sleeve rod and the elliptical rotating block to rotate. When the elliptical rotating block rotates, it can push against the two push rods and two rubber pads against the side wall inside the top cavity. This structure can restrict the position of the hemispherical stop block by rotating the rotating handle, thereby constraining the position between the circumcision device and the glans.

[0021] During the cutting process, the telescopic rod is pulled at one end according to the required cutting position to move the telescopic rod to the appropriate position. After the movement, the cutting blade is inserted into the blade holder. Then, the telescopic rod is controlled to rotate one revolution in the track constrained by the guide block to perform circumcision of the foreskin. This structure allows the circumcision position to be adjusted by the cutting blade after the foreskin anastomosis circumcision device is fixed. Attached Figure Description

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Please see as follows Figures 1-10 The circumcision device for urology shown includes a top tube 101, a tail tube 111 installed on one side of the top tube 101, a cutting blade 305 located outside the cavity of the top tube 101, and a hemispherical stop 413 located inside the cavity of the top tube 101. Both the top tube 101 and the tail tube 111 are hollow structures.

[0043] In order to limit the foreskin both during and after circumcision, such as Figures 1-5 , Figure 9As shown, a through hole 102 is provided on the side wall of the top cylinder 101, penetrating both sides. A limit rod 105 is slidably installed on the top cylinder 101 through the through hole 102. Four limit posts 103 arranged in a rectangular array are installed on the side of the top cylinder 101 away from the tail cylinder 111. Each limit post 103 is equipped with a limit stop 104. A support block 201 is provided on the side of the top cylinder 101 away from the tail cylinder 111. Four limit insertion holes 202 are provided on the side of the support block 201 near the top cylinder 101. Each limit... The positioning pins 103 are respectively inserted into one of the limiting holes 202 on the support block 201. The position of the support block 201 is limited by the cooperation of the four limiting holes 202 and the four limiting pins 103, so that its position can match the position of the top cylinder 101. The four limiting blocks 104 maintain a certain distance between the support block 201 and the top cylinder 101. The support block 201 is provided with a rotation limiting hole 203. The end of the limiting rod 105 away from the top cylinder 101 is slidably inserted into the rotation limiting hole 203 of the support block 201. Figures 4-5 It is known that there is a small buckle at one end of the limiting rod 105 that is inserted into the rotation limiting hole 203. After rotation, it can be locked in the rotation limiting hole 203 of the support block 201 to constrain the relative position between the support block 201 and the top cylinder 101. A constraint block 204 is installed on the side of the support block 201 away from the top cylinder 101. The constraint block 204 allows the foreskin to slide from the glans to the top cylinder 101 by means of the slope. Then, the upper limit collar 205 is put on the outside of the support block 201 to restrict the position of the foreskin, which is convenient for subsequent foreskin limiting and circumcision.

[0044] In order to improve the fixation effect of the circumcision device, such as Figures 1-2 , Figures 6-8As shown, two first fixing seats 112 symmetrical about the tail tube 111 are installed on the outer wall of the tail tube 111. Two slots 113 symmetrical about the center of the tail tube 111 are opened on the side wall of the tail tube 111. The two slots 113 are close to one of the first fixing seats 112 and are located on the side of the two first fixing seats 112 away from the top tube 101. A rotating handle 401 is rotatably installed on each first fixing seat 112 on the tail tube 111. A second fixing seat 402 is installed on the inner arc of each rotating handle 401. The two second fixing seats 402 are symmetrical about the tail tube 111. A connecting buckle 403 is rotatably installed on the second fixing seat 402 of each rotating handle 401. A sliding member 411 is slidably installed in the cavity of the tail tube 111. The sliding member 411 is also provided with two second fixing seats 402. The other end of the connecting buckle 403 installed on the second fixed seat 402 of the movable grip 401 is rotatably connected to one of the second fixed seats 402 on the sliding member 411. Thus, the movement of the sliding member 411 can be controlled by the two rotating grips 401. A baffle 412 for locking the top tube 101 is installed on the side wall of the sliding member 411 away from the tail tube 111. A hemispherical stop block 413 is installed on the end of the sliding member 411 away from the tail tube 111 and is slidably sleeved on the inner wall of the top tube 101. It is used to adjust the position of the device according to the position of the glans. Two springs 414 symmetrical about the sliding member 411 are installed on the side wall of the sliding member 411. A rubber pad 416 is connected to the end of the two springs 414 away from the sliding member 411. A push rod 415 that penetrates the side wall of the sliding member 411 is fixedly sleeved on the two rubber pads 416.

[0045] The sliding member 411 has a hollow structure, and an elliptical rotating block 421 is fitted inside the cavity of the sliding member 411. The shapes of the two push rods 415 are matched with the shape of the elliptical rotating block 421. When the two push rods 415 are pushed open by the elliptical rotating block 421, the two push rods 415 and the two rubber pads 416 will be squeezed against the inner wall of the top cylinder 101, which can restrict the position of the sliding member 411. A connecting rod 422 is fixed on one side of the elliptical rotating block 421. Two symmetrical limiting strips about the connecting rod 422 are installed on the side of the connecting rod 422 away from the elliptical rotating block 421. 423. A tail stop 114 is installed on the side of the tail cylinder 111 away from the top cylinder 101. A sleeve rod 431 is rotatably installed on the tail cylinder 111 via the tail stop 114. A rotating handle 432 is fixed at the end of the sleeve rod 431 away from the tail cylinder 111. The rotation of the sleeve rod 431 is controlled by rotating the handle 432. The side of the sleeve rod 431 near the connecting rod 422 is a hollow structure. The shape of the hollow structure of the sleeve rod 431 matches the shape of the connecting rod 422 and the two limiting strips 423. Thus, the rotation of the elliptical rotating block 421 can be controlled by the sleeve rod 431.

[0046] In order to allow for adjustment of the cutting position as needed after the circumcision device is fixed, such as... Figures 1-2 , Figure 10 As shown, an annular guide block 301 is fixedly sleeved on the outer wall of the top cylinder 101. A limiting slider 302 is slidably installed in the guide block 301. A telescopic rod 303 is installed on one side of the limiting slider 302. A blade locking block 304 is fixedly installed at the telescopic end of the telescopic rod 303. The cutting blade 305 is sleeved in the groove of the blade locking block 304. The tip of the cutting blade 305 points towards the top cylinder 101. After the position of the circumcision cutter is fixed, the position of the cutting blade 305 is adjusted by the telescopic rod 303 so that the circumcision position is more in line with the actual circumcision position.

[0047] During the fixation process of this urological circumcision device, pressing the two rotating handles 401 at the position of the glans causes the sliding member 411 to move towards the glans. After the sliding member 411 moves, the hemispherical stop block 413 abuts against the glans. At this time, rotating the rotating handle 432 causes the sleeve rod 431 to rotate. The sleeve rod 431 causes the connecting rod 422 and the elliptical rotating block 421 to rotate. When the elliptical rotating block 421 rotates, it can push against the two push rods 415 to pull the springs 414 outward, so that the two springs 414 are stretched. When the two push rods 415 move, they bring the two rubber pads 416 to press against the side wall inside the cavity of the top cylinder 101. The foreskin moves from the restraint block 204 along the support block 201 towards the top cylinder 101, and is fitted onto the outer wall of the top cylinder 101 through the support block 201. At this time, the foreskin is between the top cylinder 101 and the telescopic rod 303. When it moves to the appropriate position, the support block 204... 01. An upper limit collar 205 is placed on the outer foreskin. The upper limit collar 205 can restrict the foreskin on the outer wall of the support block 201. During the cutting process, the telescopic rod 303 is pulled at the telescopic end according to the position to be cut, so that the telescopic rod 303 moves to the appropriate position. After moving, the cutting blade 305 is inserted into the blade holder 304. Then, the telescopic rod 303 is controlled to rotate once in the track constrained by the guide block 301 to circumferentially cut the foreskin. After cutting with the cutting blade 305, the limiting rod 105 is rotated so that the limiting rod 105 rotates out of the groove of the rotating limiting hole 203. The limiting rod 105 can be pulled out from the rotating limiting hole 203 of the support block 201. After pulling out the limiting rod 105, the main structure of the foreskin anastomosis circumcision device can be removed. At this time, the support block 201 and the upper limit collar 205 still act on the foreskin after circumcision. Then, the foreskin at this point is sutured.

[0048] The above description is merely a preferred embodiment of the invention, but the scope of protection of the invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the invention, based on the technical solution and inventive concept of the invention, should be included within the scope of protection of the invention.
