Description

Technical Field

[0001] The invention belongs to a ureteroscope pneumatic ballistic fixing bracket. Background Art

[0002] Ureteral stones are a common disease. If not treated in time, it will lead to renal damage. Transurethral ureteroscopic ureteral stone lithotripsy is one of the main treatment methods. Among them, pneumatic ballistics and laser are the main energy platforms for crushing stones. The principle of pneumatic ballistic lithotripsy is to use the energy of compressed air to push the bullet body in the handle. The energy in the ballistics is further transferred to the striker. The striker head directly collides with the stone, causing the stone to disintegrate and achieve the purpose of stone crushing.

[0003] During the transurethral ureteroscopic pneumatic lithotripsy, the pneumatic ballistic striker needs to be partially inserted into the ureteroscope, with the tail end of the striker and the adapter located outside the ureteroscope.

[0004] During the process of pneumatic lithotripsy, the ureteroscope often needs to adjust the lithotripsy angle, which causes the ureteroscope and the tail end of the pneumatic ballistic striker to be misaligned. If the angle is too large or the misalignment is worn for a long time, the tail end of the striker will often break.

[0005] To this end, the utility model patent number CN208287046U discloses a fixing device, which mainly plays a fixing role by placing a plug directly between the pneumatic ballistic striker and the ureteroscope. Figure 1 As shown, the threaded interface 41, the spring installation cavity 42, and the guide basket 43 connected in sequence constitute an auxiliary part. The threaded interface 41 is connected to the end of the ureteroscope 1 by threading and is tightened by setting a wrench 44. A spring is arranged in the spring installation cavity 42. The guide basket 43 is a hollow cavity with an open end formed by several horizontal railings. The pneumatic ballistic handpiece 3 is placed in the guide basket 43 through the open end, and the front end of the pneumatic ballistic handpiece 3 is against the spring. The ballistic probe rod 2 is inserted into the ureteroscope 1 through the threaded interface 41. The pneumatic ballistic handpiece 3 is also provided with a finger ring 31 for driving the pneumatic ballistic handpiece 3 to move. When in use, the medical staff can hold the auxiliary part 4 with one hand, and then put the thumb in the finger ring 31, and make a similar action of pressing a mechanical pencil with the thumb, thereby driving the pneumatic ballistic handpiece 3 and the probe rod to move forward to crush the stones, and the spring performs a reciprocating motion to reset.

[0006] However, this approach has the following disadvantages:

[0007] 1. The auxiliary parts occupy the maximum extension length of the gas pressure ballistic firing pin, which reduces the extension of the head end. That is, for some shorter firing pins, the working length may not be reached. 2. When it is necessary to greatly adjust the working length of the gas pressure ballistic firing pin head end, the auxiliary parts must be detached, so that the gas pressure ballistic firing pin is no longer firmly fixed, and there is still the possibility of breaking due to uneven movement. Summary of the invention

[0008] The purpose of the present invention is to provide a ureteroscope pneumatic lithotripsy device and a fixed bracket, which can keep the pneumatic ballistic lithotripsy moving coaxially to avoid breakage while the ureteroscope is swinging during operation. In addition, the bracket can also maintain the function of freely extending and retracting the pneumatic ballistic striker in the ureteroscope while being fixed.

[0009] The technical solution adopted by the present invention to solve the above technical problems is as follows:

[0010] A ureteroscope pneumatic lithotripsy device, comprising:

[0011] A ureteroscope (1), a pneumatic ballistic handle (3) having a pneumatic ballistic striker (4), and further comprising: a fixing bracket, the fixing bracket having:

[0012] Ureteroscopic fixation part;

[0013] Handle limiting part;

[0014] One end of the ureteroscope (1) passes through the ureteroscope fixing portion, and the ureteroscope (1) is fixed by the ureteroscope fixing portion;

[0015] The pneumatic ballistic handle (3) passes through the handle limiting portion and can move freely along the limited direction of the handle limiting portion;

[0016] The ureteroscope fixing part and the handle limiting part control the ureter of the ureteroscope and the axis of the pneumatic ballistic handle to be in a straight line.

[0017] A ureteroscope pneumatic ballistic fixing bracket, comprising:

[0018] Ureteroscopic fixation part;

[0019] Handle limiting part;

[0020] One end of the ureteroscope (1) passes through the ureteroscope fixing portion, and the ureteroscope (1) is fixed by the ureteroscope fixing portion;

[0021] The pneumatic ballistic handle (3) passes through the handle limiting portion and can move freely along the limited direction of the handle limiting portion;

[0022] The ureteroscope fixing part and the handle limiting part control the ureter of the ureteroscope and the axis of the pneumatic ballistic handle to be in a straight line.

[0023] After the present invention adopts the above-mentioned scheme, it does not affect the maximum extension length of the pneumatic ballistic firing pin, and when the working length of the firing pin needs to be adjusted, there is no need to loosen the fixer, which has a better effect.

[0024] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the written description and the accompanying drawings.

[0029] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that as long as there is no conflict, the various embodiments of the present invention and the various features in the embodiments can be combined with each other, and the technical solutions formed are all within the protection scope of the present invention.

[0030] like Figure 1 As shown, a ureteroscope pneumatic lithotripsy device with an auxiliary component in the prior art is shown, which mainly adds an auxiliary component to the existing ureteroscope pneumatic lithotripsy device.

[0031] The present invention adds an auxiliary fixing bracket to the existing ureteroscope pneumatic lithotripsy device. Figure 2 , which is a schematic diagram of an embodiment of a fixing bracket according to an embodiment of the present invention; Figure 3 The figure shows a schematic diagram of the structure of the ureteroscope pneumatic lithotripsy device of the present invention.

[0032] The ureteroscope pneumatic ballistic lithotripsy device comprises: a ureteroscope (1), a pneumatic ballistic handle (3) having a pneumatic ballistic striker (4), which are all prior art and will not be described in detail. In addition, it also comprises: a fixed bracket, the fixed bracket having:

[0033] A ureteroscope fixing part, used for fixing the ureteroscope (1);

[0034] A handle limiter, used for controlling the movement direction of the pneumatic ballistic handle (3);

[0035] The ureteroscope fixing part and the handle limiting part are provided with a connecting frame part, and the ureteroscope fixing part and the handle limiting part are connected together through the connecting frame part.

[0036] One end of the ureteroscope (1) passes through the ureteroscope fixing portion, and the ureteroscope (1) is fixed by the ureteroscope fixing portion;

[0037] The pneumatic ballistic handle (3) passes through the handle limiting portion and can move freely along the limited direction of the handle limiting portion;

[0038] The ureteroscope fixing part and the handle limiting part control the ureter of the ureteroscope and the axis of the pneumatic ballistic handle to be in a straight line.

[0039] Among them, Figure 2 and Figure 3 In an embodiment of the present invention, the ureteroscope fixing portion is a clasp (7), and the outer diameter of the ureter of the ureteroscope (1) is the same as the inner diameter of the clasp (7), thereby enabling the ureter of the ureteroscope (1) to be fixed by the clasp (7).

[0040] A clamping ring gasket (8) is arranged between the ureter and the clamping ring (7).

[0041] The clamping ring gasket (8) prevents the ureter from being squeezed and damaged when the ureteroscope is directly fixed to the clamping ring.

[0042] The handle limiting portion is a cylindrical working ring (11), the outer diameter of the pneumatic ballistic handle is in contact with the inner diameter of the working ring (11), and the pneumatic ballistic handle can freely pass through the working ring (11).

[0043] Generally speaking, through the above design, the size of the pneumatic ballistic handle can be just enough to pass freely in the ring. When the ureteroscope is swung, the working ring can make the pneumatic ballistic swing at the same time to avoid the occurrence of misalignment and the breakage of the firing pin.

[0044] In order to achieve the effect that the axes of the ureter and the pneumatic ballistic handle are in a straight line, in a preferred embodiment, the axes of the clamping ring (7) and the working ring (11) are in a straight line.

[0045] In the present application, the fixed support (2) is fixedly connected to the ureteroscope (1) via the head clamp (7), and is connected to the pneumatic ballistic handle via the working ring (11), that is, the pneumatic ballistic extends into the working ring for operation without affecting the normal operation of the pneumatic ballistic.

[0046] Through the above design, the pneumatic ballistics can be kept coaxially moving when the ureteroscope is swung, and the bracket can also maintain the function of telescopic adjustment of the pneumatic ballistic striker in the ureteroscope while being fixed. It does not affect the maximum extension length of the pneumatic ballistic striker, and when the working length of the striker needs to be adjusted, there is no need to loosen the fixator, which has a better effect.

[0047] In addition, if Figure 2 As shown, the clamping ring (7) is composed of two semicircular rings, and the two ends of the semicircular rings have connecting ends respectively, and a fixing nut (6) is passed through the middle of the connecting end. A rotating reinforcement knob (5) is provided at the end of the fixing nut (6), thereby fixing the two semicircular rings together.

[0048] The connecting frame assembly comprises: two connecting frames (9) of equal length, at least one reinforcing crossbeam (10) being arranged between the two connecting frames (9). In one embodiment, the two connecting frames (9) of equal length are connected together via a rotating shaft component.

[0049] Preferably, a triangular structure is formed between the reinforcing cross beam (10) and the connecting frame (9). Of course, depending on the number of reinforcing cross beams, the connecting portion can also be designed into a quadrilateral or other shapes. Of course, the cross beam portion can also be directly removed or increased to 2 or 3 beams.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
