Description

Technical Field

[0001] The utility model relates to the technical field of pet urethra scalpels, in particular to a urethra minimally invasive scalpel which is convenient for realizing the rotation and tilting of a blade. Background Art

[0002] Currently, urinary retention due to urethral stricture is a common urological disease in the field of pet clinical medicine. This is especially true for male cats, whose urethra is relatively narrow. Once urinary retention develops, it can lead to death within a few days, with a very high mortality rate. The main causes of urinary retention in pets include: (1) stones or crystals blocking the urethra or ureter; (2) spontaneous cystitis; (3) urinary tract infection; and (4) urinary retention caused by stress. Traditional solutions for pet urinary retention are urethrostomy or oral medication. However, traditional urethrostomy methods have many side effects, and oral medication is slow to take effect.

[0003] In the prior art, of course, there are also treatment methods that use an endourethral incision knife for surgical cutting. For example, the Chinese invention patent application number is CN201520758495.4, which discloses an endourethral incision knife, including a cylindrical hollow knife rod, a guide wire running through the interior of the knife rod from beginning to end, and an arc-shaped blade provided on one side of the knife rod. The knife rod and the blade are an integrated structure, and the blade is protrudingly provided on one side of the knife rod. Due to the protruding fixing method of the blade relative to the knife rod, the overall width of the endourethral incision knife is invisibly increased, so that the doctor needs to be particularly careful when inserting the endourethral incision knife into the pet's narrow urethra to prevent the normal part of the pet's urethra from being cut. Moreover, the speed of the surgical operation must be slowed down, otherwise the straight and hard knife rod and blade will be quickly inserted into the pet's narrow urethra, which can easily cause the urethra to be scratched, making the surgical cutting operation more difficult and inconvenient to use. Utility Model Content

[0004] The purpose of the utility model is to provide a minimally invasive urethra knife that is easy to rotate and tilt the blade, aiming to solve the technical problems of the existing urethra knife being difficult to operate and inconvenient to use.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the present invention provides a minimally invasive urethra knife that facilitates the rotation and tilting of the blade, comprising:

[0006] An insertion rod body, wherein a receiving groove is provided on one side of the insertion rod body along its length direction, and a hollow cavity is provided inside the insertion rod body along its length direction, and the insertion rod body has a first end and a second end;

[0007] a cutting blade rotatably received in the receiving groove, wherein the receiving groove is in communication with the hollow cavity of the insertion rod; and

[0008] An injection device is connected to the second end of the insertion rod body, so as to inject liquid or gas into the hollow cavity of the insertion rod body through the injection device to drive the cutting blade to rotate and emerge from the mouth of the receiving groove.

[0009] Furthermore, the cutting blade has a stored state and an exposed state. When the cutting blade is in the stored state, the cutting blade is accommodated in the accommodating groove, and the length direction of the cutting blade is roughly parallel to the length direction of the insertion rod body. When the cutting blade is in the exposed state, the length direction of the cutting blade is set at an angle to the length direction of the insertion rod body, and the angle between one end of the cutting blade and the first end of the insertion rod body is greater than 0 degrees and less than 90 degrees.

[0010] Furthermore, when the cutting blade is in the storage state, one end of the cutting blade close to the first end of the insertion rod body is rotatably installed in the insertion rod body, and one end of the cutting blade close to the second end of the insertion rod body serves as the cutting end.

[0011] Furthermore, when the cutting blade is in an exposed state, the side of the cutting blade close to the first end of the insertion rod body abuts against the end of the receiving groove close to the first end of the insertion rod body, and the side of the cutting blade away from the first end of the insertion rod body is provided with a cutting edge.

[0012] Furthermore, when the cutting blade is in the retracted state, one end of the cutting blade close to the first end of the insertion rod body is rotatably mounted in the insertion rod body, so that the liquid injected by the injection device impacts the one end of the cutting blade away from the first end of the insertion rod body, thereby driving the cutting blade to rotate and expose.

[0013] Furthermore, it also includes a mounting rod, which has a mounting groove on one side of the mounting rod facing the receiving groove. The mounting groove is arranged corresponding to the receiving groove, so that one end of the cutting blade can be rotatably installed in the mounting groove and the mounting rod can be inserted into the insertion rod body to thereby rotatably install the cutting blade in the insertion rod body, and the insertion rod body is a bendable hose structure.

[0014] Furthermore, the mounting rod is made of metal material, and the insertion rod body is made of soft plastic material.

[0015] In addition, the technical solution of the present invention provides a minimally invasive urethra knife that facilitates the rotation and tilting of the blade, comprising:

[0016] An insertion rod body, wherein a receiving groove is formed on one side of the insertion rod body along its length direction, and the insertion rod body has a first end and a second end;

[0017] a cutting blade rotatably accommodated in the receiving groove;

[0018] In which, the cutting blade has a stowed state and an exposed state. When the cutting blade is in the stowed state, the cutting blade is accommodated in the receiving groove, and the end of the cutting blade close to the first end of the insertion rod body is rotatably installed in the receiving groove, and the end of the cutting blade away from the first end of the insertion rod body serves as the cutting end, so that the cutting end is at least partially exposed from the receiving groove through the cutting end and the end of the receiving groove close to the second end of the insertion rod body; when the cutting blade is in the exposed state, the side of the cutting blade close to the first end of the insertion rod body abuts against the end of the receiving groove close to the first end of the insertion rod body, and the side of the cutting blade away from the first end of the insertion rod body is provided with a blade.

[0019] Furthermore, when the cutting blade is in an exposed state, the length direction of the cutting blade is set at an angle to the length direction of the insertion rod body, and the angle between one end of the cutting blade and the first end of the insertion rod body is greater than 0 degrees and less than 90 degrees.

[0020] Furthermore, the insertion rod body is a bendable soft rod structure.

[0021] It can be seen from the above technical solution that the urethral minimally invasive knife of the utility model is easy to realize the rotation and tilting of the blade. By hiding the cutting blade in the receiving groove of the insertion rod body, the insertion rod body carrying the cutting blade can be inserted more smoothly into the narrow pet urethra. When the cutting blade reaches the pet's bladder, liquid is injected into the insertion rod body through the injection device to drive the cutting blade to rotate and emerge from the mouth of the receiving groove. Then, the surgical cutting operation can be performed to pull the insertion rod body and drive the cutting blade to cut the narrow and blocked part of the pet's urethra. The structure is simple and easy to operate, convenient for cutting the pet's urethra, and effectively simplifies the difficulty of surgical cutting.

[0039] In order to enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0040] Please also refer to Figures 1 to 6 The present embodiment provides a minimally invasive urethra scalpel that facilitates the rotation and tilting of the blade, comprising:

[0041] The insertion rod body 100 has a receiving groove 110 formed on one side of the insertion rod body 100 along its length. The receiving groove 110 is a long strip-shaped groove, and a hollow cavity is formed inside the insertion rod body 100 along its length. The insertion rod body 100 has a first end and a second end. The first end is a closed end 120, and the second end is an open end 130.

[0042] The cutting blade 200 is rotatably received in the receiving groove 110 , and the receiving groove 110 is connected to the hollow cavity of the insertion rod 100 ; and

[0043] The injection device 300 is connected to the open end 130 of the insertion rod body 100, so as to inject liquid into the hollow cavity of the insertion rod body 100 through the injection device 300, thereby driving the cutting blade 200 to rotate and emerge from the mouth of the receiving groove 110, wherein the injected liquid can be water or a chemical liquid, and the chemical liquid can be an anti-inflammatory liquid or a bactericidal and disinfectant liquid. In this way, the liquid injected by the injection device 300 can not only drive the cutting blade 200 to emerge from the receiving groove 110, but also can sterilize and disinfect the surgical incision site. The pet is a pet cat.

[0044] It can be seen that the urethral minimally invasive knife of the first embodiment, which is convenient for realizing the rotation and tilting of the blade, hides the cutting blade 200 in the receiving groove 110 of the insertion rod body 100, so that the insertion rod body 100 carrying the cutting blade 200 can be inserted more smoothly into the narrow pet urethra. After the cutting blade 200 reaches the pet's bladder, liquid is injected into the insertion rod body 100 through the injection device 300 to drive the cutting blade 200 to rotate and be exposed from the mouth of the receiving groove 110. Then, the surgical cutting operation can be performed to pull the insertion rod body 100 and drive the cutting blade 200 to cut the narrow and blocked part of the pet's urethra. The structure is simple and easy to operate, convenient for cutting the pet's urethra, and effectively simplifies the difficulty of surgical cutting.

[0045] In this embodiment, the cutting blade 200 has a storage state and an exposed state. When the cutting blade 200 is in the storage state, the cutting blade 200 is accommodated in the receiving groove 110, and the length direction of the cutting blade 200 is roughly parallel to the length direction of the insertion rod body 100. In this way, in the storage state, the cutting blade 200 is hidden in the receiving groove 110 to facilitate insertion into the narrow urethra of the pet. When the cutting blade 200 is in the exposed state, the length direction of the cutting blade 200 is set at an angle to the length direction of the insertion rod body 100, and the angle between one end of the cutting blade 200 and the closed end 120 of the insertion rod body 100 is greater than 0 degrees and less than 90 degrees, so that the cutting blade 200 is tilted toward the closed end 120 of the insertion rod body 100 in the exposed state. In this way, when the insertion rod body 100 is pulled outward and drives the cutting blade 200 to cut the narrow blocked part of the pet's urethra, the cutting blade 200 abuts against one end of the receiving groove 110 close to the closed end 120 of the insertion rod body 100.

[0046] Specifically, when the cutting blade 200 is in the storage state, the end of the cutting blade 200 close to the closed end 120 of the insertion rod body 100 is rotatably installed in the insertion rod body 100, and the end of the cutting blade 200 close to the open end 130 of the insertion rod body 100 serves as the cutting end. In this way, the cutting end of the cutting blade 200 can rotate and be exposed from the mouth of the receiving groove 110 under the impact of the liquid injected by the injection device 300.

[0047] Furthermore, when the cutting blade 200 is in an exposed state, the side of the cutting blade 200 close to the closed end 120 of the insertion rod body 100 abuts against the end of the receiving groove 110 close to the closed end 120 of the insertion rod body 100, and the cutting end of the cutting blade 200 is provided with a blade 210 on the side away from the closed end 120 of the insertion rod body 100 to facilitate cutting the narrow inner wall of the pet's urethra.

[0048] In this embodiment, when the cutting blade 200 is in the retracted state, one end of the cutting blade 200 close to the closed end 120 of the insertion rod body 100 is rotatably mounted in the insertion rod body 100, so that the liquid injected by the injection device 300 impacts the end of the cutting blade 200 away from the closed end 120 of the insertion rod body 100, thereby driving the cutting blade 200 to rotate outward and expose itself.

[0049] Specifically, the urethral minimally invasive knife that facilitates the rotation and tilting of the blade also includes a mounting rod 400. A mounting groove 410 is provided on the side of the mounting rod 400 facing the receiving groove 110. The mounting groove 410 extends along the length direction of the mounting rod 400, and the mounting groove 410 is arranged corresponding to the receiving groove 110, so that one end of the cutting blade 200 can be rotatably installed in the mounting groove 410 and the mounting rod 400 is inserted into the insertion rod body 100, so that the cutting blade 200 can be rotatably installed in the insertion rod body 100. The insertion rod body 100 is a hose structure. In this way, the insertion rod body 100 adopts a flexible hose structure, which can adapt to the curvature of the pet's urethra without affecting the smooth insertion into the pet's urethra, thereby avoiding damage to the pet's urethra caused by inserting a straight hard rod.

[0050] Furthermore, the mounting rod 400 is made of metal material, and the insertion rod body 100 is made of soft plastic material. The insertion rod body 100 is preferably made of PVC or PE soft plastic material. In this way, when the insertion rod body 100 is a hose, the cutting blade 200 is installed through the mounting rod 400, avoiding the rotational mounting structure of the cutting blade 200 from being affected, thereby reducing the difficulty of structural assembly.

[0051] Preferably, the mounting rod 400 is fixed to the inner wall of the insertion rod body 100 by bonding or hot melting. The insertion rod body 100 is a hollow tube structure, and a hemispherical end is blocked at one end of the hollow tube to form a closed end 120. During production and assembly, the mounting rod 400 and the cutting blade 200 can be inserted into the insertion rod body 100 from one end of the hollow tube, and the cutting blade 200 is set corresponding to the receiving groove 110, and then the hemispherical end is blocked and fixed to one end of the hollow tube. The hemispherical end can effectively reduce the damage caused to the pet's urethra when inserted into the pet's urethra.

[0052] In this embodiment, through holes are correspondingly provided on the opposite side walls of the mounting groove 410, and a through hole 220 is provided at one end of the cutting blade 200, so that the cutting blade 200 can be accommodated in the mounting groove 410 and inserted into the two through holes and the through hole 220 through a pin rod 230, so that the cutting blade 200 can be rotatably installed in the mounting groove 410, wherein the length extension direction of the pin rod 230 is arranged perpendicular to the length extension direction of the mounting rod 400, so that the cutting blade 200 can rotate around the pin rod 230.

[0053] Furthermore, the open end 130 of the insertion rod body 100 is provided with a connecting tube mouth 131, which can be detachably engaged with the injection port of the injection device 300 through the connecting tube mouth 131. The injection device 300 is a manual syringe or an automatic injection device 300. The automatic injection device 300 can use a water pump or an air pump. The injection device 300 preferably uses a manual syringe, so that the liquid injected by the manual syringe drives the cutting blade 200 to rotate outward and expose it. The manual syringe is an existing injection component, and its specific structure and principle will not be described in detail here.

[0054] Please also refer to Figures 7 to 11 The second embodiment provides a minimally invasive urethra knife that facilitates the rotation and tilting of the blade, including:

[0055] The insertion rod body 100 has a receiving groove 110 formed on one side of the insertion rod body 100 along its length direction, and the insertion rod body 100 has a first end and a second end;

[0056] The cutting blade 200 is rotatably accommodated in the receiving groove 110;

[0057] Among them, the cutting blade 200 has a storage state and an exposed state. When the cutting blade 200 is in the storage state, the cutting blade 200 is accommodated in the receiving groove 110, and the end of the cutting blade 200 close to the first end of the insertion rod body 100 is rotatably installed in the receiving groove 110, and the end of the cutting blade 200 away from the first end of the insertion rod body 100 serves as the cutting end, so that the cutting end is at least partially exposed from the receiving groove 110 through the cutting end and the end of the receiving groove 110 close to the second end of the insertion rod body 100; when the cutting blade 200 is in the exposed state, the side of the cutting blade 200 close to the first end of the insertion rod body 100 is abutted against the end of the receiving groove 110 close to the first end of the insertion rod body 100, and the side of the cutting blade 200 away from the first end of the insertion rod body 100 is provided with a blade 210.

[0058] It can be seen that the urethral minimally invasive knife of the second embodiment is easy to realize the rotation and tilting of the blade. When the cutting blade 200 is in the storage state, the cutting blade 200 is hidden in the receiving groove 110, so that the first end of the insertion rod 100 can be more smoothly inserted into the narrow pet urethra. When the cutting blade 200 reaches the pet's bladder, the insertion rod 100 is pulled outward, so that the cutting end at least partially exposed from the receiving groove 110 is against the pet's urethra wall, thereby driving the cutting blade 200 to rotate and switch from the storage state to the exposure state. Subsequently, the surgical cutting operation can be performed to pull the insertion rod 100 outward and drive the blade 210 of the cutting blade 200 to cut the narrow and blocked part of the pet's urethra. The structure is simple and easy to operate, convenient for cutting the pet's urethra, and effectively simplifies the difficulty of surgical cutting.

[0059] Specifically, when the cutting blade 200 is in the exposed state, the length direction of the cutting blade 200 is set at an angle to the length direction of the insertion rod body 100, and the angle between one end of the cutting blade 200 and the first end of the insertion rod body 100 is greater than 0 degrees and less than 90 degrees. The insertion rod body 100 is a flexible soft rod structure made of soft plastic material, and a hollow cavity is provided inside the insertion rod body 100 along its length direction. The receiving groove 110 is connected to the hollow cavity of the insertion rod body 100, as shown in FIG. Figure 11 As shown, the cutting blade 200 can be installed in the soft insertion rod body 100 through the installation rod 400. Please refer to the relevant description of the above embodiment 1, and the specific structure of the installation rod 400 will not be described in detail here.

[0060] It is worth mentioning that the structure of the second embodiment is roughly the same as that of the first embodiment, and reference may be made to the description of the same structure in the first embodiment. The main difference is that the second embodiment cancels the injection device 300, and when the cutting blade 200 is in the storage state, the cutting end of the cutting blade 200 is at least partially exposed from the receiving groove 110 to form a barb-like structure, so that when the insertion rod 100 is pulled outward, the cutting end of the cutting blade 200 is blocked by the pet's urethra wall to force the cutting end of the cutting blade 200 to rotate and switch to the exposed state. The structure is simple, the design is novel, and it is easy to produce and process. In particular, since the urethra of pet cats is very narrow, the insertion rod 100 used is not easy to be inserted. The inlet tube 100 is also very slender, and the space inside the insertion rod body 100 is relatively narrow. Generally, it is not possible to directly connect the cutting blade 200 through structural design in industrial production to push the cutting blade 200 to rotate and expose. The solution of the first embodiment uses the injection device 300 to inject liquid into the insertion rod body 100, thereby driving the cutting blade 200 to rotate and expose from the mouth of the receiving groove 110. The solution of the second embodiment omits the injection device 300 and cleverly utilizes the working environment of the cutting blade 200 to realize the rotation of the cutting blade 200 through surgical operation to switch to the exposed state. The design is very clever, easy to implement in industrial production, and easy to use.
