Description

Technical Field

[0001] The present application relates to the technical field of medical auxiliary instruments, and in particular to a multifunctional probe hook used in arthroscopic surgery, which can not only assist in detecting tissue obstructions and measuring lengths within joints, but also discharge fluid accumulated in the joint cavity. Background Art

[0002] Minimally invasive surgery on human bones and joints is different from conventional open surgery. For example, in the clinical operation of arthroscopic surgery, many special surgical instruments must be prepared, such as tissue graspers, thread removers, basket forceps, probe hooks and other arthroscopic surgery-specific instruments. Among them, the probe hook is an essential basic operating tool. If the tissue inside the joint is blocked or deep exploration is required, the probe hook is needed to assist. It is equivalent to the doctor's fingers and is used to explore the tension, toughness or traction of tissues during surgery.

[0003] During arthroscopic surgery, the patient's joints need to be observed and treated to understand the size of the lesion and then determine the treatment plan. There is no scale on the existing probe hook, which is not conducive to length observation. Chinese patent document CN 201921395370.4 discloses a scaled arthroscopic probe hook, which mainly solves the following technical problems: During arthroscopic surgery, because the structure or bone canal in the joint cannot be directly observed by the naked eye, a mobile C-arm X-ray machine is sometimes required to assist. However, the length and other data of the observed object cannot be directly seen under the X-ray, and the surgeon can only estimate based on experience. However, this observation method brings about large errors, which may prolong the operation time, increase the risk of infection, or cause other negative effects on the operation results. In order to solve the above problems, the probe hook disclosed in the above patent document includes a handle, a long handle and a short handle; one end of the handle is fixedly connected to one end of the long handle, and the other end of the long handle is provided with a short handle at a 90-degree angle thereto, and the long handle is provided with parallel annular grooves as scales at regular intervals from the junction with the short handle; the short handle is 5 mm long and also provided with annular grooves, and the spacing between the annular grooves is 1 mm. Since the probe hook disclosed in the above patent document is provided with parallel annular grooves as scales at regular intervals, the surgeon can accurately observe the size of the lesion.

[0004] Although the probe hook disclosed in the above patent document is provided with a scale to facilitate accurate observation by the physician, it still has the following defects: there is fluid accumulation in the joint cavity during surgery, and the existing probe hook cannot remove the accumulated fluid. The surgeon needs to replace the operating instrument, and then replace the probe hook again to continue observation after the accumulated fluid is discharged. Frequent replacement of instruments leads to cumbersome operation and low efficiency.

[0005] In order to solve the above-mentioned technical problems, the applicant filed a utility model patent on May 29, 2023, with the patent name of a probe hook for arthroscopic surgery, and the patent publication number is CN219680687U. The probe hook disclosed in the document includes a detection part and a drainage part connected to the detection part. The first measuring rod and the second measuring rod constituting the detection part are both provided with scales, which can be used for length measurement; the drainage part includes a hollow long tube, one end of the hollow long tube is connected to the second measuring rod; a plurality of drainage holes are formed on the side wall of the hollow long tube close to the second measuring rod, which can be used to introduce joint cavity effusion into the long tube; a drainage outlet is provided on the side wall close to the other end of the hollow long tube, and a cap is provided at the end of the hollow long tube, and an opening corresponding to the drainage outlet is provided on the cap, and the cap is rotatably connected to the hollow long tube, and the drainage outlet and the opening can be aligned or misaligned and closed by rotating the cap. The probe hook disclosed in this patent can not only be used for length measurement, but also can drain fluid from the joint cavity. It has multiple uses and is easy to use. It minimizes the frequency of doctors replacing auxiliary equipment and reduces the complexity of operations.

[0006] Although the probe hook disclosed in the above patent document can solve the above technical problems, the applicant is committed to continuous technological innovation in this sub-sector and believes that the probe hook disclosed in the above patent document can still be improved. Therefore, this application proposes a new technical solution to solve the problems existing in the prior art. Utility Model Content

The angle between the first probe rod 1 and the second probe rod 2 is arbitrary, but in the present application, the angle between the first probe rod 1 and the second probe rod 2 is preferably 90°, which is convenient for use and measurement.

[0049] The structures of the first detection rod 1 and the second detection rod 2 are described in detail below.

[0050] 1. The first probe rod

[0051] In this embodiment, the length of the first detection rod 1 is shorter than the second detection rod 2. Both detection rods are made of stainless steel. The length of the first detection rod 1 can be 3mm, 3.5mm or 4mm. Of course, it can be set longer or shorter according to different situations.

[0052] The first detection rod 11 is provided with a scale line every 1 mm, such as Figure 6 , the scale lines are used to measure the length. In this embodiment, the first detection rod 1 is preferably a solid cylinder with an outer diameter of 1.5 mm, and the free end surface of the first detection rod 11 can also be set as a spherical surface.

[0053] In other embodiments, the first detection rod 1 may also be a solid elliptical cylinder structure, and the major axis of its cross section may be set to 1.5 mm, or the minor axis of its cross section may be set to 1.5 mm.

[0054] 2. Second detection rod

[0055] In this embodiment, the second detection rod 2 is an integrally formed tubular member. Therefore, a drainage channel is formed in the second detection rod 2 along its axial direction. The two end pipe openings of the second detection rod 2 respectively form an end water inlet hole 212 and a tail drainage hole 232. Figure 4 , 5 .

[0056] In this embodiment, the second detection rod 2 is composed of a detection cone pipe section 21, a handle extension pipe section 22 and a tail drainage pipe section 23 which are connected in sequence, and the three pipe sections are integrally formed.

[0057] 1. Detection cone pipe section 21: It is a cone-shaped column pipe section, see Figure 3 The outer diameter of the detection cone tube section 21 gradually increases from the end connected to the first detection rod 1 to the end connected to the handle extension tube section 22, and a plurality of drainage holes 211 are provided on it. The drainage holes 211 are connected to the drainage channel formed by the tube cavity of the second detection rod 2. A scale line (not shown) is provided on the tube wall of the detection cone tube section 21 every 1 mm.

[0058] In this embodiment, the length of the detection cone tube section 21 can be set to 3.5 cm, and a scale line is set on the tube wall every 1 mm, and scale numbers can be set every 1 cm. During specific processing, the detection cone tube section 21 can be engraved with multiple continuous scale numbers "1, 2, 3" by laser, which is intuitive and convenient for observation.

[0059] In this embodiment, see Figure 3The multiple drainage holes 211 on the detection cone tube section 21 are round holes, and the aperture range of the drainage holes 211 is 1.0mm to 1.5mm. From the end of the detection cone tube section 21 connected to the first detection rod 1 to the end of the detection cone tube section 21 connected to the handle extension tube section 22, the aperture of the drainage hole 211 can be regularly increased. Of course, the aperture of the drainage hole 211 can also remain unchanged, and can be customized according to actual processing conditions.

[0060] In this embodiment, a plurality of drainage holes 211 are staggeredly distributed on the detection cone tube section 21. The drainage holes 211 on one side of the tube wall of the detection cone tube section 21 are staggered with the drainage holes 211 on the other side of the tube wall, that is, each drainage hole 211 is unilaterally conductive on the tube wall.

[0061] During specific processing, a plurality of drainage holes 211 may be dispersed on the detection cone tube section 21 in a spiral shape.

[0062] 2. Handle extension pipe section 22: The handle extension pipe section 22 is between the detection cone pipe section 21 and the tail drainage pipe section 23, which is convenient for doctors to hold when in use. Specifically, a hand-held portion is formed on the handle extension pipe section 22, and the hand-held portion includes a handle sleeve 221 sleeved on the handle extension pipe section 22, and the end of the handle sleeve 221 abuts against the end of the tail cap 3, such as Figure 2 , 9 In this embodiment, the handle extension tube section 22 is preferably a cylindrical tube with an outer diameter of 3 mm, the length of the handle sleeve 221 is set to 7 cm, the handle sleeve 221 includes a cylindrical tube and a conical tube arranged on one side of the cylindrical tube, the inner diameter of the cylindrical tube is 3 mm, the outer diameter of the cylindrical tube is 6 mm, the cone angle of the conical tube is 30°, and the length of the conical tube is 5 mm.

[0063] 3. Tail drainage pipe section 23: A drainage port 231 is provided on the pipe wall of the tail drainage pipe section 23, on which a tail cap 3 is adapted to be provided. Figure 2 The tail cap 3 is provided with an opening 31 corresponding to the drain port 231. Figure 7 , 8 The tail cap 3 can close the tail drainage hole 232 at the end of the tail drainage pipe section 23. The tail cap 3 is plug-in connected to the tail drainage pipe section 23. In this embodiment, the tail drainage pipe section 23 is preferably a cylindrical pipe. The tail cap 3 is plugged into the tail drainage pipe section 23 and can rotate. By rotating the tail cap 3, the drainage port 231 and the opening 31 can be aligned or closed.

[0064] In this embodiment, the tail cap 3 is plugged and sleeved on the tail drainage pipe section 23. The shape, size and opening position of the opening on the tail cap 3 are all adapted to the drainage port 231. The drainage port 231 is a strip-shaped drainage port 231. The tail cap 3 is a cylindrical structure with one end open and the other end closed. The tail cap 3 is provided with a mounting groove 32 adapted to be plugged with the tail drainage pipe section 23. The notch of the mounting groove 32 is provided with a circle of flared chamfer 33. The flared chamfer 33 is provided to facilitate the installation of the tail cap 3.

[0065] In a specific processing example, the end face of the end of the detection cone tube section 21 connected to the first detection rod 1 is a circular end face, the outer diameter of the circular end face is 1.8mm, and the inner diameter is 1.1mm. The cross section of the end of the detection cone tube section 21 connected to the handle extension tube section 22 is a circular ring, with an outer diameter of 3.0mm and an inner diameter of 1.1mm. The length of the detection cone tube section 21 is 3.5cm, and a scale line is set at every 1mm interval. The scale line can be a ring line set along the axial direction of the tube wall; the handle extension tube section 22 is a cylindrical tube, and the outer diameter of the handle extension tube section 22 is 3.0m m, the inner diameter is 1.1mm, the length of the handle sleeve 221 on the handle extension pipe section 22 is 7cm, and the end of the handle sleeve 221 abuts against the end of the tail cap 3; the tail drainage pipe section 23 is a cylindrical tube, the outer diameter of the tail drainage pipe section 23 is 3.0mm, the inner diameter is 1.1mm, the length of the strip drainage port 231 thereon is 1.5cm~2.5cm, preferably 2cm, and the aperture of the tail drainage hole 232 at its end is 1.1mm; the length of the tail cap 3 is 3cm, and during the processing process, the total length of the second detection rod 2 with the tail cap 3 installed is ensured to be 20cm.

[0066] Since the probe hook is used in joint cavity surgery with a narrow operating range, its structure must be as slender as possible so that it can penetrate into the affected area to assist the doctor in the operation. The probe hook provided in this application meets the doctor's operating scenarios.

[0067] According to measurements made by the inventors during actual surgery, the drainage hole 211 provided on the side wall of the second detection rod 2 should be less than or equal to 8 cm away from the end of the detection cone tube section 21. The drainage hole 211 provided beyond 8 cm has no clinical use significance, as it will be higher than the liquid surface in the joint cavity. Once exposed to the water surface, it will destroy the sealing of the second detection rod 2 during use, affecting the realization of pressure drainage.

[0068] In this embodiment, a sealing ring may be further provided in the mounting groove 32 formed on the tail cap 3 , and when the tail end of the second detection rod 2 is inserted into the tail cap 3 , the sealing ring may play a sealing role.

[0069] In this embodiment, the drain port 231 is a long strip hole. The shape of the opening on the tail cap 3 is the same as that of the drain port 231 , and the size of the opening is larger than that of the drain port 231 , which is convenient for draining liquid.

[0070] When using the probe hook provided by the present application for surgery, the doctor holds the handle sleeve 221 on the handle extension tube section 22, uses the tail cap 3 to close the drainage port 231 on the tail drainage tube section 23, extends the probe hook into the patient's joint cavity, and measures the size of the lesion through the first probe rod 1 and the second probe rod 2. The effusion in the joint cavity enters the tube cavity of the second probe rod 2 from the several drainage holes 211 on the detection cone tube section 21 and the end water inlet of the detection cone tube section 21. After use, the tail cap 3 can be rotated so that the drainage port 231 is aligned with the opening on the tail cap 3 and is connected, and the effusion in the second probe rod 2 is discharged from the drainage port 231. Therefore, the probe hook provided by the present application has multiple functions, which can not only read intuitively through the scale but also discharge the effusion in the joint cavity, and reduce the frequency of the surgeon changing auxiliary instruments according to the needs during the operation as much as possible, reduce the cumbersomeness of the operation, ensure the continuity of the doctor's operation as much as possible, and improve the efficiency of the operation.
