Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a reduction and fixation component for trauma orthopedics. Background Art

[0002] Traumatology orthopedics is a branch of orthopedics that focuses on fractures, dislocations, ligament injuries, etc. caused by trauma. Traumatology orthopedics often uses external fixators when treating fractures and other bone injuries. External fixators provide effective fixation in fracture treatment, maintain bone continuity, promote fracture healing, and avoid the occurrence of complications such as delayed bone healing, bone nonunion, and re-fracture.

[0003] During the use of the external fixator, the doctor will perform percutaneous puncture on the patient, pass the steel needle or steel nail through the skin and muscle to fix it on the bone, and then connect the punctured steel needle or steel nail to the connecting rod or frame of the external fixator. The connecting rod or frame can be made of metal or plastic. They connect the exposed ends of the steel needles to form a stable fixation mechanism. After the external fixator is fixed, a longer part of the exposed end of the steel nail or steel needle will be exposed outside the patient's body. The length of the exposed end of the steel nail or steel needle is uncontrollable, and one end of the steel nail or steel needle must be exposed outside the patient's body, because when the steel nail or steel needle is removed later, it is necessary to use tools with the help of its exposed end to twist the steel nail or steel needle out of the patient's body.

[0004] Because the bone healing process is relatively long, patients need to wear external fixators for a long time during the rehabilitation stage. During the long-term wearing of external fixators, the exposed steel nails or steel needles not only occupy a large space, affecting the normal living and walking of patients, but also the ends of the steel nails or steel needles are relatively sharp. When patients wear clothes and cover themselves with quilts in bed, the exposed ends of the steel nails or steel needles will scrape against the clothes or quilts, which can easily tear the clothes and quilts, causing inconvenience to patients. Therefore, the present invention provides a reduction and fixation assembly for trauma orthopedics to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a reduction and fixation component for trauma orthopedics, which can provide a wrapping protection for the exposed end of the steel nail. The wrapping effect ensures that the exposed end of the steel nail will not affect the patient's normal daily life. The protection component also wraps the corners of the external support, so that during the patient's walking exercise, the body squeezing or rubbing against the surface of the external support will not affect the position of the steel nail, thereby avoiding the phenomenon of tearing and bleeding between the steel nail and the patient's skin. The above arrangement can solve the problem that the exposed end of the steel nail affects the patient's normal life during the use of the external fixator.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A reduction and fixation assembly for trauma orthopedics comprises an outer bracket, on which a splint is mounted, and steel nails are inserted into the splint and the outer bracket; and a protection assembly, which is used to wrap and protect the exposed ends of the steel nails and is connected to the steel nails and the splint, respectively.

[0008] Optionally, the protection component includes a hose sleeved on the top of the steel nail, one end of the hose is fixedly connected to a cushion, and the outer sleeve of the steel nail is provided with a press clip.

[0009] Optionally, an outer sleeve is fixedly connected to the bottom of the hose, an inner sleeve is fixedly connected inside the outer sleeve, and an inner skeleton matching the contour of the inner sleeve is installed between the outer sleeve and the inner sleeve.

[0010] Optionally, the inner sleeve is a curved corrugated structure, one end of the inner skeleton is fixedly connected to an outward-turned frame sheet, and the outward-turned frame sheet and the inner skeleton are both segmented structures.

[0011] Optionally, a plurality of first weakened grooves are provided at the connection position between the externally-turned frame piece and the internal frame, and a pulling wire is fixedly connected between the top of the internal frame piece and one end of the externally-turned frame piece.

[0012] Optionally, an insert block is fixedly connected to the bottom of the cushion, an adapting slot matching the outline of the insert block is formed on the splint, and a first cavity is formed in the insert block.

[0013] Optionally, a first buffer cavity is provided at the top of the cushion, second buffer cavities are provided at both sides of the cushion, a second cavity is provided at the bottom of the cushion, and a connecting hole is provided between the first buffer cavity and the second cavity.

[0014] Optionally, a pressing portion is fixedly connected to the middle position of the pressing clip, a covering portion is fixedly connected to the bottom of the pressing clip, and a through hole is opened through one side of the pressing clip.

[0015] Optionally, a V-shaped groove is symmetrically provided on the top of the pressing clip, and a second weakened groove is provided on a side of the pressing clip opposite to the through hole.

[0016] Optionally, the extrusion portion has an inwardly concave curvature, the thickness of the extrusion portion is greater than the thickness of the covering portion, the cross-sectional profile of the covering portion is C-shaped, and the top of the pressing clip has an outwardly convex curvature.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, by setting up a protection component, the exposed end of the steel nail can be wrapped for protection, and the effect achieved by the wrapping is that the exposed end of the steel nail will not affect the patient's normal daily life. The protection component also wraps the corners of the external bracket, so that during the patient's walking exercise, the body squeezing or rubbing against the surface of the external bracket will not affect the position of the steel nail, thereby avoiding the phenomenon of tearing and bleeding between the steel nail and the patient's skin. In addition, the protection component also performs protective treatment on the contact position between the steel nail and the patient's skin, and the effect achieved by the treatment further protects the skin at the position of the steel nail to prevent bleeding and infection. The protection component comprehensively considers the impact of the external fixator on the patient's life and activities during use from different directions, and uses a simple and ingenious structure to solve many problems, providing patients with a more comfortable and safe wearing experience.

[0019] By setting a hose in the protective component, not only can the steel nails be wrapped and protected, but also the gaps between each steel nail can be connected, thereby ensuring that the patient will not be affected by the exposed ends of the steel nails during the wearing of the external fixator, thereby reducing the patient's psychological burden and wearing pressure.

[0020] By arranging an outer sleeve and an inner sleeve in the protective component, when the patient puts the hose on the steel nail, the steel nail can first be inserted into the inner sleeve with the aid of the guiding positioning of the bottom arc-shaped structural contour of the outer sleeve, and then the steel nail can be limited and fixed with the help of the clamping force of the inner sleeve. The setting of multiple corrugated structural contours can not only improve the fixing effect of the inner sleeve on the steel nail, but also ensure that the steel nail and the hose will not be detached during use.

[0021] By arranging an inner frame and an outer frame in the protective component, the inner sleeve and the outer sleeve can only assist in fixing the steel nail, ensuring that the steel nail and the hose will not separate. In addition, the inner frame and the outer frame can increase the strength of the structure of the inner sleeve and the outer sleeve, preventing the inner sleeve and the outer sleeve from tearing and wearing during long-term use, thereby improving the service life of the two and the fixing effect on the steel nail.

[0022] By arranging a cushion in the protection component, not only can the patient's comfort level in the process of wearing the external fixator be improved, but also different degrees of impact force and extrusion force can be absorbed and buffered, thereby reducing the braking effect of the extrusion force and impact force on the external bracket, preventing the steel nails and the patient's skin surface from tearing and bleeding, and when the cushion buffers the impact force or extrusion force, the cushion can increase the stability of the fit between the cushion and the splint by means of the deformation effect of the cushion itself, thereby strengthening the stability of the overall structure of the cushion in the process of buffering and absorbing the impact force and extrusion force, and preventing the cushion from being displaced or detached due to strong impact.

[0023] By providing a compression clip in the protective component, not only can the patient's skin be isolated from the outside world, but it can also have a certain protective effect, reduce the frequency of skin bleeding and infection, and improve the safety and comfort of the external fixator during the entire wearing process.

[0045] like Figures 1 to 12 As shown, an embodiment of the present invention provides a reduction and fixation assembly for trauma orthopedics, including an external support 1, a splint 101 is installed on the external support 1, and steel nails 102 are inserted on the splint 101 and the external support 1; a protection assembly, the protection assembly is used to wrap and protect the exposed ends of the steel nails 102, and the protection assembly is connected to the steel nails 102 and the splint 101 respectively. The external fixator provided by the present application is mainly used to protect the fracture points at the lower leg of the human body. Specifically, the protection assembly can wrap the exposed ends of the steel nails 102 for protection, and the effect achieved by the wrapping is that the exposed ends of the steel nails 102 will not affect the normal daily life of the patient. The protection assembly is also provided at the corners of the external support 1. The wrapping ensures that when the patient is walking and exercising, the compression or friction of the body against the surface of the external support 1 will not affect the position of the steel nail 102, thus avoiding tearing and bleeding between the steel nail 102 and the patient's skin. In addition, the protection component also performs protective treatment on the contact position between the steel nail 102 and the patient's skin. The effect achieved by the treatment further protects the skin at the position of the steel nail 102 to prevent bleeding and infection. The protection component comprehensively considers the impact of the external fixator on the patient's life and activities during use from different directions, and uses a simple and ingenious structure to solve many problems, providing patients with a more comfortable and safe wearing experience.

[0046] As an implementation method in this embodiment, Figures 1 to 6As shown, the protection component includes a hose 2 sleeved on the top of the steel nail 102, the bottom of the hose 2 is fixedly connected to an outer sleeve 201, the inner sleeve 201 is fixedly connected to an inner sleeve 202, an inner skeleton 3 that matches the contour of the inner sleeve 202 is installed between the outer sleeve 201 and the inner sleeve 202, the inner sleeve 202 is a curved corrugated structure, one end of the inner skeleton 3 is fixedly connected to an outer frame sheet 301, the outer frame sheet 301 and the inner skeleton 3 are both segmented structures, a plurality of first weakened grooves 302 are provided at the connection position between the outer frame sheet 301 and the inner skeleton 3, and a top of the inner skeleton 3 and one end of the outer frame sheet 301 are fixedly connected. A pulling wire 303 is connected, and the hose 2 is sleeved on the top of each steel nail 102 to wrap up the sharp part of the exposed end of the steel nail 102. The hose 2 is made of rubber and has a cylindrical structure as the overall profile. Such a configuration not only makes the hose 2 softer, but also makes the surface profile more rounded. Therefore, when the hose 2 is sleeved on the exposed end of the steel nail 102, it can not only wrap and protect the steel nail 102, but also connect the gaps between each steel nail 102, thereby ensuring that the patient will not be affected by the exposed end of the steel nail 102 during the process of wearing the external fixator, thereby reducing the patient's psychological burden and wearing pressure.

[0047] In order to facilitate the patient to more efficiently and conveniently sleeve and fix the hose 2 on the exposed end of the steel nail 102, an outer sleeve 201 is installed at the bottom of the hose 2. The outer sleeve 201 has a curved conical profile, and the bottom of the outer sleeve 201 has an arc-shaped structure inclined inward, and the inner sleeve 202 extends from one end of the bottom of the outer sleeve 201. Therefore, the outer sleeve 201 and the inner sleeve 202 are an integrated structure, and the cross-sectional profile of the inner sleeve 202 is a corrugated structure, and the cross-sectional size of the inner sleeve 202 is smaller than the cross-sectional size of the steel nail 102. This arrangement allows the patient to use the inner sleeve The contour of the corrugated structure 202 clamps and fixes the top of the steel nail 102. When the patient puts the outer sleeve 201 on the steel nail 102, the steel nail 102 can first be inserted into the inner sleeve 202 with the aid of the bottom arc-shaped structural contour of the outer sleeve 201 to assist in guiding and positioning. Then, the steel nail 102 is limited and fixed with the help of the clamping force of the inner sleeve 202. The setting of multiple corrugated structural contours can not only improve the fixing effect of the inner sleeve 202 on the steel nail 102, but also ensure that the steel nail 102 and the hose 2 will not be detached during use.

[0048] Furthermore, there is a gap between the inner sleeve 202 and the outer sleeve 201, and an inner frame 3 is installed in the gap. The inner frame 3 is made of plastic. The inner frame 3 made of plastic is not only inexpensive but also light in weight. The overall contour of the inner frame 3 matches the contour of the inner sleeve 202. An outer frame piece 301 extends from one end of the bottom of the inner frame 3. The overall structural contour of the outer frame piece 301 matches the contour of the outer sleeve 201. The inner frame 3 and the outer frame piece 301 are placed in the gap between the outer sleeve 201 and the inner sleeve 202, which can not only It plays a supporting role with good adaptability, and the inner frame 3 and the outer frame piece 301 made of plastic material are stronger and have better torsion and pulling resistance than the outer sleeve 201 and the inner sleeve 202 made of rubber material, thereby ensuring that the inner sleeve 202 and the outer sleeve 201 will not cause structural damage and deformation due to friction and pulling between the steel nail 102 during long-term use, thereby affecting the fixing effect of the inner sleeve 202 and the outer sleeve 201 on the steel nail 102. In addition, a pulling wire 303 is installed between the inner frame 3 and the outer frame piece 301, and the pulling wire 303 is The arrangement of 3 makes the structure between the inner frame 3 and the outer frame piece 301 more integrated and stronger, ensuring that the inner frame 3 and the outer frame piece 301 still have a good supporting effect on the inner sleeve 202 and the outer sleeve 201 during long-term use. The first weakening groove 302 is opened at the connection position between the inner frame 3 and the outer frame piece 301. The first weakening groove 302 weakens the connection position between the two, so that the inner frame 3 and the outer frame piece 301 are more likely to be elastically deformed at the position of the first weakening groove 302. This arrangement is to cooperate with The corrugated structure of the inner sleeve 202 assists in fixing the steel nail 102. The above structural arrangement enables the inner skeleton 3 and the outer frame piece 301 to not only assist the inner sleeve 202 and the outer sleeve 201 in fixing the steel nail 102, thereby ensuring that the steel nail 102 and the hose 2 will not separate, but also the inner skeleton 3 and the outer frame piece 301 can increase the structural strength of the inner sleeve 202 and the outer sleeve 201, thereby preventing the inner sleeve 202 and the outer sleeve 201 from tearing and wearing during long-term use, thereby improving the service life of the two and the fixing effect on the steel nail 102.

[0049] In this embodiment, if Figures 1 to 3 and Figures 7 to 9As shown, one end of the hose 2 is fixedly connected with a cushion 203, the bottom of the cushion 203 is fixedly connected with an insert block 204, the clamping plate 101 is provided with an adapting slot 103 adapted to the contour of the insert block 204, the insert block 204 is provided with a first cavity 205, the top of the cushion 203 is provided with a first buffer cavity 206, the two sides of the cushion 203 are provided with second buffer cavities 207, the bottom of the cushion 203 is provided with a second cavity 208, a connecting hole 209 is provided between the first buffer cavity 206 and the second cavity 208, the cushion 203 and the hose 2 are made of the same material, and the cushion 203 extends from one end of the hose 2, so the cushion 203 and the hose 2 are an integrated structure manufactured uniformly during the production process, and the cushion 20 The soft pad 203 is inserted and fixed into the adapter slot 103 on the splint 101 through the plug block 204. The installation position of the soft pad 203 is located at the top of the external support 1, which is at the connection position of the calf and the knee joint. The patient needs to perform walking training during the entire rehabilitation process to increase the blood circulation at the fracture site, which is beneficial to the repair of the fracture site. The patient needs to bend his legs and knees during the walking training. The patient's skin is easily squeezed onto the splint 101 at the top of the external support 1 during the bending of the legs and knees. The squeezing force on the splint 101 will not only affect the fixing effect of the external support 1 on the steel nail 102, but also easily cause the steel nail 102 to be pulled on the patient's skin surface, thereby causing the patient's skin to bleed. The setting of the soft pad 203 can be very good. To solve the above problems, specifically, the cushion 203 is not only made of rubber material with a soft structure, but also the overall structure has rounded corners, so that the cushion 203 is soft and more comfortable at the corners, so that the patient's skin will not feel uncomfortable when it is squeezed or hit against the surface of the cushion 203. In addition, a plurality of first buffer cavities 206 and second buffer cavities 207 are provided in the cushion 203. The first buffer cavities 206 are provided on the outer side of the cushion 203 and are arranged equidistantly in an elliptical structure. The second buffer cavities 207 are mainly located at the corners of the cushion 203 and are in a rectangular structure. The second cavity 208 is located on the inner side of the cushion 203. When an extrusion force or an impact force is generated on the surface of the cushion 203, the first buffer cavities 206 and the second buffer cavities 207 are firstly The cavity 207 will be squeezed and deformed accordingly. During the deformation of the two, part of the impact force and the squeeze force can be absorbed and buffered, thereby reducing the braking effect of the impact force or the squeeze force on the external bracket 1. A first cavity 205 is set in the plug block 204. The first cavity 205 and the second cavity 208 are connected through a connecting hole 209. The first buffer cavity 206 and the second cavity 208 are also connected through the connecting hole 209. Then, as the first buffer cavity 206 is squeezed and deformed, the air inside the first buffer cavity 206 will enter the second cavity 208, and then the air inside the second cavity 208 will enter the first cavity 205 through the connecting hole 209. The final effect is that the first cavity 205 is expanded and deformed.Thus, the insertion between the plug block 204 and the adapter slot 103 is more stable and firm. When a stronger impact force appears on the surface of the splint 101, the first buffer cavity 206 and the second buffer cavity 207 are deformed. When the two reach the maximum deformation limit, the second cavity 208 is squeezed and deformed accordingly, and the impact force is buffered to achieve a multi-level buffering effect. The above structure allows the cushion 203 to not only improve the comfort of the patient in the process of wearing the external fixator, but also absorb and buffer the impact force and the squeezing force of different degrees, thereby reducing the braking effect of the squeezing force and the impact force on the external bracket 1, and preventing the steel nail 102 and the patient's skin from tearing and bleeding. In addition, when the cushion 203 buffers the impact force or the squeezing force, the deformation effect of the cushion 203 itself can be used to increase the stability of the cooperation with the splint 101, thereby strengthening the stability of the overall structure of the cushion 203 in the process of buffering and absorbing the impact force and the squeezing force, and preventing the cushion 203 from being dislocated or separated due to a strong impact.

[0050] In this embodiment, if Figure 1 , Figure 2 and Figures 10 to 12As shown, the steel nail 102 is covered with a pressing clip 4, a pressing portion 401 is fixedly connected to the middle position of the pressing clip 4, a covering portion 402 is fixedly connected to the bottom of the pressing clip 4, a through hole 404 is penetrated through one side of the pressing clip 4, a V-shaped groove 403 is symmetrically opened on the top of the pressing clip 4, a second weakened groove 405 is opened on the side of the pressing clip 4 opposite to the through hole 404, the pressing portion 401 has an inwardly concave arc, the thickness of the pressing portion 401 is greater than the thickness of the covering portion 402, the cross-sectional profile of the covering portion 402 is C-shaped, and the top of the pressing clip 4 has an outwardly convex arc. When the patient wears the external fixator, the steel nail 102 needs to penetrate the skin and pierce into the bone. During the entire treatment process, the skin at the puncture position of the steel nail 102 is always exposed to the outside, so bleeding and infection often occur. In particular, during exercise and training, the patient's skin often bleeds due to the compression between the muscle and the steel nail 102. In order to protect the skin at the puncture position of the steel nail 102, a pressing clip 4 is arranged on the outer sleeve of the steel needle. The pressing clip 4 is mainly divided into three parts. One part is a sheet located at the top of the pressing clip 4. The top sheet has an outwardly rolled profile, and two V-shaped grooves 403 are symmetrically opened on the top of the pressing clip 4. Under the action of the V-shaped grooves 403, the sheet at the top of the pressing clip 4 is divided into two; one part is an extrusion part 401 located in the middle of the pressing clip 4. The extrusion part 401 is 01 has an inwardly concave profile, and its thickness is greater than the thickness of other positions of the pressing clip 4; the other part is a covering portion 402 located at the bottom of the pressing clip 4, and the cross-sectional profile of the covering portion 402 is a C-shaped structure. A through hole 404 is formed through one side of the entire pressing clip 4, and the through hole 404 is located at the position of one of the V-shaped grooves 403. A second weakening groove 405 is formed on one side of the covering portion 402, and the second weakening groove 405 is formed on the side opposite to the through hole 404.

[0051] Specifically, since the covering portion 402 has a C-shaped contour, the patient can place the disposable disinfection cotton inside the covering portion 402 with the help of its semi-wrapped structure, and then slide the pressing clip 4 to allow the disposable disinfection cotton to press and protect the patient's skin. Furthermore, since the squeezing portion 401 in the middle position of the pressing clip 4 has an inwardly concave arc structure, the patient can use this contour to clamp the pressing clip 4 outside the steel nail 102. When the height of the pressing clip 4 needs to be adjusted, it is only necessary to slide the pressing clip 4 up and down to allow the covering portion 402 to contact the patient's skin surface, and fix the position of the pressing clip 4 with the help of the clamping effect of the squeezing portion 401. This not only isolates the patient's skin from the outside world, but also has a certain protective effect, reducing the frequency of skin bleeding and infection. The rate is high. If bleeding occurs, the disposable disinfection cotton can also absorb the blood to prevent blood stains from contaminating clothes. Furthermore, when the patient needs to remove the pressing clip 4 from the steel nail 102, the pressing clip 4 can be pulled to both sides along the position of the through hole 404 to allow the pressing clip 4 to expand along the position of the through hole 404. After the pressing clip 4 is expanded, the pressing clip 4 can be removed from the steel nail 102. Since the second weakened groove 405 is provided on the side opposite to the through hole 404, the patient will save more effort in the process of swinging the pressing clip 4. Since the top of the pressing clip 4 has an outwardly turned arc, the user can use the contour of the top of the pressing clip 4 when swinging the pressing clip 4 and sliding the pressing clip 4 up and down, so that the patient can take and put the pressing clip 4 more conveniently and efficiently.

[0052] The working principle of the technical solution provided by the present invention is as follows: when in use, the steel nail 102 is first passed through the patient's skin and fixed to the bone, and then the exposed end of the steel nail 102 is limited and fixed by means of the external bracket 1. When the steel nail 102 is fixed, the steel needle is squeezed by the splint 101 and the screw, and finally the effect of fixing and reducing the fracture position of the patient is achieved. After the positions of the steel nail 102 and the external bracket 1 are fixed, the cushion 203 and the hose 2 are fixed on the top of the splint 101 and the steel nail 102 respectively. Specifically, align the outer sleeve 201 and the inner sleeve 202 at the bottom of the hose 2 with the top of the steel nail 102, then directly press the hose 2, insert the steel nail 102 into the hose 2 along the inner sleeve 202, and put the hose 2 on the top of each steel nail 102, and wrap up the sharp part of the exposed end of the steel nail 102. Since the material of the hose 2 is rubber and the overall profile is a cylindrical structure, when the hose 2 is put on the exposed end of the steel nail 102, it can not only wrap and protect the steel nail 102, but also Moreover, the gaps between each steel nail 102 are connected, thereby ensuring that the patient will not be affected by the exposed ends of the steel nails 102 during the process of wearing the external fixator, thereby reducing the patient's psychological burden and wearing pressure. The cross-sectional profile of the inner sleeve 202 is a corrugated structure, and the cross-sectional size of the inner sleeve 202 is smaller than the cross-sectional size of the steel nail 102. This arrangement allows the patient to clamp and fix the top of the steel nail 102 with the help of the contour of the corrugated structure of the inner sleeve 202. The inner frame 3 and the outer frame plate 30 1 is placed in the gap between the outer sleeve 201 and the inner sleeve 202, which can not only provide a good support for the inner sleeve 202 and the outer sleeve 201, but also the inner frame 3 and the outer frame sheet 301 made of plastic material have higher strength and better torsion and pulling resistance than the outer sleeve 201 and the inner sleeve 202 made of rubber material, thereby ensuring that the inner sleeve 202 and the outer sleeve 201 will not be damaged or deformed due to friction and pulling between the steel nail 102 during long-term use.

[0053] The cushion 203 is not only made of rubber material with a soft structure, but also the overall structure has rounded corners, which makes the cushion 203 soft and more comfortable at the corners, so that the patient's skin will not feel uncomfortable when it is squeezed or hit against the surface of the cushion 203. The cushion 203 is provided with a first buffer cavity 206, a second buffer cavity 207 and a second cavity 208. When a strong impact force appears on the surface of the splint 101, the first buffer cavity 206 and the second buffer cavity 207 are deformed, and the impact force can be absorbed and buffered during the deformation process. When the two reach the maximum deformation limit, the second cavity 208 is squeezed and deformed accordingly, and the impact force is buffered again, thereby achieving a multi-level buffering effect, reducing the braking effect of the squeezing force and the impact force on the external bracket 1, and preventing the steel nail 102 and the patient's skin surface from tearing and bleeding.

[0054] The pressing clip 4 is sleeved on the outside of the steel nail 102. The patient can put the disposable disinfection cotton inside the covering part 402 with the help of the semi-wrapped structure of the covering part 402, and then slide the pressing clip 4 to allow the disposable disinfection cotton to press and protect the patient's skin. Furthermore, since the squeezing part 401 in the middle position of the pressing clip 4 has an inwardly concave arc structure, the patient can use this contour to clamp the pressing clip 4 outside the steel nail 102. When the height of the pressing clip 4 needs to be adjusted, it is only necessary to slide the pressing clip 4 up and down, so that the covering part 402 is in contact with the patient's skin surface, and the position of the pressing clip 4 is fixed with the help of the clamping effect of the squeezing part 401. This not only isolates the patient's skin from the outside world, but also has a certain protective effect, reducing the frequency of skin bleeding and infection. The rate is high. If bleeding occurs, the disposable disinfection cotton can also absorb the blood to prevent blood stains from contaminating clothes. Furthermore, when the patient needs to remove the pressing clip 4 from the steel nail 102, the pressing clip 4 can be pulled to both sides along the position of the through hole 404 to allow the pressing clip 4 to expand along the position of the through hole 404. After the pressing clip 4 is expanded, the pressing clip 4 can be removed from the steel nail 102. Since the second weakened groove 405 is provided on the side opposite to the through hole 404, the patient will save more effort in the process of swinging the pressing clip 4. Since the top of the pressing clip 4 has an outwardly turned arc, the user can use the contour of the top of the pressing clip 4 when swinging the pressing clip 4 and sliding the pressing clip 4 up and down, so that the patient can take and put the pressing clip 4 more conveniently and efficiently.
