Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a prostate hyperplasia gland stripper. Background Art

[0002] Prostatic hyperplasia (BPH) also known as benign prostatic hyperplasia (BPH) has two main symptoms: bladder irritation and obstructive symptoms caused by the enlarged prostate blocking the urinary tract. Bladder irritation symptoms include frequent urination, urgency, increased nocturia, and urge incontinence. Frequent urination is an early sign of BPH, and increased nocturia is particularly clinically significant. The disease has three main features: an enlarged prostate; bladder outlet obstruction; and lower urinary tract symptoms such as dysuria, frequent urination, and urgency. In existing technologies, the blade movement mode of traditional dissection tools is single, making it difficult to penetrate into various parts of the complex anatomical structure of the prostate. In particular, when dealing with deep glandular tissue, the position and direction cannot be flexibly adjusted, resulting in difficulty in completely dissecting some hyperplastic tissue. Furthermore, the tool lacks multi-directional operation capabilities and can only advance in a single direction, failing to address the dissection requirements of both the glandular surface and deep tissue, thus affecting surgical effectiveness and efficiency. Furthermore, existing dissectors lack the ability to simultaneously clean tissue, and the removed tissue easily accumulates within the surgical field of view, hindering subsequent operations and requiring the surgeon to interrupt the operation for cleaning. This not only prolongs the operation time but also increases the risk of infection. Therefore, in response to the above-mentioned existing technical problems, this solution proposes a prostate hyperplasia gland stripper. Summary of the Invention

[0003] In order to solve the above-mentioned problems in the prior art, the present invention designs a prostate hyperplasia gland stripper. A rotatable stripping assembly is provided at the front end of a support tube. By adjusting the stripping assembly to rotate to different positions, the surface and deep hyperplastic tissues can be stripped respectively. A scraping assembly is provided at the lower end. By controlling the scraping assembly to extend and retract, the stripped tissue is scraped to prevent the surgical field of view from being blocked. In order to achieve the above technical effects, the present invention is implemented through the following technical solutions: a prostate hyperplasia gland stripper, comprising: a support component, a stripping component, and a scraping component; The scraping assembly is provided at the lower end of the support assembly, and the stripping assembly is provided at the upper end; The stripping assembly includes a rotating seat, a rotating shaft, a worm gear, a worm, a rotating knob, a stripping head, a stripping rod, and a motor; a rotating shaft is provided in the middle of the rotating seat to rotate and connect the support assembly, and a slot is provided on the upper end to set the motor; a worm gear is provided on one side of the rotating shaft; a stripping rod is provided on the upper end of the motor; a stripping head is provided on the upper end of the stripping rod; the worm is rotatably connected to the support assembly, the front end engages with the worm gear, and the rear end penetrates the support assembly to set the rotating knob; Furthermore, the stripping head is configured as a tapered blade head, with a tapered front end and gradually widening at the rear end; Furthermore, the support assembly includes a support cylinder, a rotating cylinder, a scraping groove, a stripping seat, and a scraping plate; the upper portion of the support cylinder is hollow, and the scraping plate is provided at the lower portion; the scraping plate is provided with a scraping groove in the middle portion thereof for sliding connection with the scraping assembly, and the stripping seat is symmetrically provided on both sides of the upper end for rotational connection with a rotating shaft; Furthermore, a rotating cylinder is provided on one side of the upper end of the support cylinder to rotatably connect to the worm, and a side cut groove is provided on the upper part of the front end to movably connect to the peeling rod; Furthermore, the rear end of the scraper plate is configured to be hollow; Furthermore, the scraping assembly includes a scraping blade, a scraping rod, a telescopic rod, a support plate, a spring, a handle, and an adjustment assembly; sliders for slidingly connecting the scraping rod are symmetrically arranged at both ends of the scraping blade; an adjustment assembly is arranged in the middle of the scraping rod, and a telescopic rod is arranged at the rear end to be slidably connected to the support plate; a handle is arranged at the lower end of the support plate, the lower end of the handle penetrates the support tube, and a spring is arranged at the front end to be fixedly connected to the rear end of the scraping blade; Furthermore, a groove is provided at the lower portion of the rear end of the support tube for slidingly connecting the handle; Furthermore, the adjustment assembly includes an adjustment seat, an adjustment screw, an adjustment knob, a slider, and an adjustment block; a transverse groove is provided at the rear end of the scraper plate, an adjustment seat is provided in the middle of the transverse groove and is rotatably connected to the adjustment screw, and sliders are symmetrically provided at both ends; a hole is provided in the middle of the slider and is slidably connected to the scraper rod; an adjustment block is provided at the upper end of the slider and is threadedly connected to the adjustment screw; one end of the adjustment screw penetrates the support tube and is provided with an adjustment knob; Furthermore, the thread pitches on the adjusting blocks on both sides are the same, and the thread rotation directions are opposite.

[0004] The beneficial effects of the present invention are: The present invention uses a conical stripping head to perform conventional stripping of the glandular surface tissue in a parallel and forward direction. The invention can also rotate the worm by rotating the knob, thereby driving the worm wheel to rotate, so that the stripping head rotates to the side and penetrates deep into the gland to perform deep tissue stripping. This overcomes the problems of traditional stripping tools with a single movement mode and limited operation direction. It can flexibly adapt to the complex anatomical structure of the prostate and achieve all-round and precise resection of hyperplastic tissue at different locations and depths, effectively improving the thoroughness of the operation and reducing the risk of postoperative recurrence. At the same time, the distance between the scraping rods on both sides is controlled by adjusting the component, thereby controlling the bending of the scraping blade, and the scraping blade is driven to extend and retract by pressing the handle, so that the tissue can be scraped off in time after being peeled off, avoiding the accumulation of tissue fragments that block the surgical field of view, reducing the number of surgical interruptions, shortening the operation time, and reducing the chance of complications such as infection.

[0008] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0009] Example 1 like Figure 1 、 2 As shown, the scraping component 3 is provided at the lower end of the support component 1, and the stripping component 2 is provided at the upper end; The stripping assembly 2 includes a rotating base 201, a rotating shaft 202, a worm gear 203, a worm 204, a rotating knob 205, a stripping head 206, a stripping rod 207, and a motor 208; a rotating shaft 202 is provided in the middle of the rotating base 201 to rotatably connect to the support assembly 1, and a slot is provided at the upper end to set the motor 208; a worm gear 203 is provided on one side of the rotating shaft 202; a stripping rod 207 is provided at the upper end of the motor 208; a stripping head 206 is provided at the upper end of the stripping rod 207; the worm 204 is rotatably connected to the support assembly 1, the front end engages with the worm gear 203, and the rear end penetrates the support assembly 1 to set the rotating knob 205; the worm gear 203 and worm 204 transmission mechanism have a self-locking function, which can ensure that the stripping head 206 remains stable at the set angle to prevent accidental rotation during the operation; Furthermore, the stripping head 206 is configured as a tapered blade head, with a tapered front end and gradually widening at the rear end; this facilitates the blade head to penetrate the glandular tissue, and is suitable for situations where it is necessary to start cutting from a specific location, or to perform local excision deep inside the gland. The tapered design can help the doctor more accurately control the starting point and direction of cutting, and has a unique advantage when treating hyperplastic tissue deep in the gland or in narrow areas. It facilitates precise penetration of the glandular tissue, and the wide rear end provides a larger force-bearing area during cutting, thereby improving cutting efficiency. like Figure 2 、 3As shown, the support assembly 1 includes a support cylinder 101, a rotating cylinder 102, a scraping groove 104, a stripping seat 105, and a scraping plate 106; the upper part of the support cylinder 101 is set to be hollow, and the scraping plate 106 is set at the lower part; the scraping groove 104 is set in the middle of the scraping plate 106 to slide and connect the scraping assembly 3, and the stripping seats 105 are symmetrically set on both sides of the upper end to rotate and connect the rotating shaft 202. Furthermore, a rotating cylinder 102 is provided on one side of the upper end of the support cylinder 101 to rotatably connect to the worm 204, and a side cut groove 103 is provided on the upper front end to movably connect to the peeling rod 207; the side cut groove 103 is a reserved channel for the rotation of the peeling rod 207 and limits the rotation range of the peeling rod 207; Furthermore, the rear end of the scraper plate 106 is set to be hollow; providing space for the installation of the handle 307 and the spring 306, ensuring that the spring 306 can be connected to the scraper plate 106, and the automatic retraction of the scraper plate is achieved by the elasticity of the spring 306; like Figures 4-8 As shown, the scraping assembly 3 includes a scraping blade, a scraping rod, a telescopic rod 303, a support plate 305, a spring 306, a handle 307, and an adjustment assembly 304; the scraping blade is symmetrically provided with sliders 3044 for sliding connection with the scraping rod at both ends; the adjustment assembly 304 is provided in the middle of the scraping rod, and the telescopic rod 303 is provided at the rear end for sliding connection with the support plate 305; the handle 307 is provided at the lower end of the support plate 305, the lower end of the handle 307 penetrates the support tube 101, and the front end is provided with a spring 306 for fixing the rear end of the scraping blade 106; In this embodiment, the scraping blade is in the shape of an arc-shaped thin sheet and has a certain elasticity. The edge is finely ground and has a good scraping effect. Furthermore, a groove is provided at the lower portion of the rear end of the support tube 101 to slideably connect a handle 307, so that when performing a scraping operation, the scraping plate 106 at the front end is driven to extend and retract by the sliding handle 307 to scrape the peeled tissue. like Figure 6 、 7 As shown, the adjustment assembly 304 includes an adjustment seat 3041, an adjustment screw 3042, an adjustment knob 3043, a slider 3044, and an adjustment block 3045; a transverse groove is provided at the rear end of the scraper plate 106, an adjustment seat 3041 is provided in the middle of the transverse groove for rotatably connecting to the adjustment screw 3042, and sliders 3044 are symmetrically provided at both ends; a hole is provided in the middle of the slider 3044 for slidably connecting to the scraper rod; an adjustment block 3045 is provided at the upper end of the slider 3044 for threaded connection to the adjustment screw 3042; one end of the adjustment screw 3042 penetrates the support tube 101 and is provided with an adjustment knob 3043; Furthermore, the thread pitches on the adjustment blocks 3045 on both sides are the same, and the thread rotation directions are opposite; In this embodiment, the working principle of the device is as follows: the doctor inserts the support tube 101 into the prostate area through the urethra, uses the support component 1 as the gripping basis, and realizes the coordinated operation of peeling and scraping through mechanical transmission; In the stripping assembly 2, the worm 204 is rotated by rotating the knob 205. The worm 204 engages with the worm wheel 203 to rotate the rotating shaft 202, thereby allowing the rotating base 201 to drive the stripping head 206 to adjust the angle within the range of 0°-90°: when the stripping head 206 is at 0°, it can strip the surface layer of the gland parallel to the urethra axis and forward; when it is rotated to the side angle, it can penetrate deep into the gland for layered cutting. The motor 208 is installed on the top of the rotating base 201, driving the stripping rod 207 to drive the conical stripping head 206 to rotate. The blade design with a sharp front end and gradually widened rear end allows precise penetration and efficient cutting of hyperplastic tissue. In the scraping assembly 3, when the adjusting knob 3043 is turned, the adjusting screw 3042 rotates and drives the adjusting blocks 3045 on both sides with opposite thread rotation directions to move synchronously toward or away from each other, and the scraping rod is pushed by the slider 3044 to adjust the distance between the scraping rods on both sides, thereby controlling the bending angle of the front scraping blade. When not in use, the scraping blade is adjusted to the widest position so that it is in a state close to horizontal to prevent affecting the peeling operation; during the operation, the depth of the scraped tissue can be controlled by adjusting the curvature of the scraping blade. The doctor drives the telescopic rod 303 by pressing the handle 307, so that the scraping rod slides along the scraping groove 104 of the scraping plate 106, thereby realizing the extension and retraction of the scraping blade to clean the peeled tissue fragments. The blade at the front end of the scraping plate 106 can cut off the tightly adhered tissue. The spring 306 provides a reset elastic force for the handle 307, so that the scraping blade automatically rebounds to the initial position after the handle 307 is released.

[0010] Example 2 In this embodiment, the material selection of the peeling sheet must take into account biocompatibility, mechanical properties, and processing technology. In actual use, the following materials are more suitable: Titanium alloy (Ti-6Al-4V): tensile strength reaches 895MPa and density is only 4.43g / cm 3 , much lower than stainless steel (7.85g / cm 3 ), reducing the overall weight of the device, and the TiO2 passivation film formed on its surface can resist corrosion from human body fluids and avoid tissue reactions caused by ion precipitation; When the device needs to change the bending angle of the scraping blade through the adjustment component 304, the titanium alloy material can withstand the stress generated by repeated bending, avoid cracking or deformation due to fatigue, and ensure the accuracy of bending adjustment and structural durability. In the process of repeatedly adjusting the bending angle to control the scraping depth, the titanium alloy component is not prone to plastic deformation and always maintains the preset bending shape; Furthermore, the elongation of titanium alloy is ≥10%, allowing the material to undergo elastic or plastic deformation within a certain range without breaking. This characteristic enables the stripping blade or scraping rod to easily change its angle by external force when adjusting its curvature, while also stably maintaining its curved shape after adjustment, thus avoiding difficulty in adjustment or angle rebound due to excessive brittleness of the material. When it is necessary to increase the bending angle of the scraping blade by reducing the distance between the scraping rods on both sides by adjusting component 304, the titanium alloy material can deform evenly with the change in distance, ensuring that the bending angle precisely corresponds to the adjustment amount. When the curved parts of the device come into contact with human tissue, the elastic deformation ability of titanium alloy can buffer local stress and reduce stress concentration caused by excessive rigidity, thereby ensuring that the force of bending adjustment is controllable and reducing the risk of additional damage to tissue.

[0011] In summary, the present invention can perform conventional stripping of the glandular surface tissue by moving the conical stripping head 206 parallel to the front. The worm 204 can also be rotated by rotating the knob 205, thereby driving the worm wheel 203 to rotate, so that the stripping head 206 can be rotated to the side to penetrate deep into the gland to perform deep tissue stripping. This overcomes the problems of traditional stripping tools with a single movement mode and limited operation direction. It can flexibly adapt to the complex anatomical structure of the prostate, achieve all-round and precise resection of hyperplastic tissue at different locations and depths, effectively improve the thoroughness of the operation, and reduce the risk of postoperative recurrence. At the same time, the distance between the scraping rods on both sides is controlled by adjusting the component 304, thereby controlling the bending of the scraping blade, and the scraping blade is driven to extend and retract by pressing the handle 307, so that the tissue is scraped off in time after being peeled off, avoiding the accumulation of tissue fragments that block the surgical field of view, reducing the number of surgical interruptions, shortening the operation time, and reducing the chance of complications such as infection.
