Description

Technical Field

[0001] The utility model relates to the field of dressing fixing devices, in particular to a fracture traction nail dressing positioning device. Background Art

[0002] In clinical practice, fracture stent external fixation is one of the most common surgeries in orthopedic surgery. Fracture stent external fixation is able to avoid damage to the soft tissues at the fracture ends, especially the periosteum, so as to effectively prevent the lack of blood circulation at the fracture ends, which may lead to slow bone growth in the later stage, or even nonunion, bone necrosis, etc. Therefore, it is particularly suitable for closed reduction and external fixation of some fractures or for some open fractures. When the soft tissue damage around the fracture is relatively serious and it is not suitable for internal fixation or internal fixation infection, it is more appropriate to use an external fixator. With the advancement of medicine, bone transport is often chosen in cases of fracture end damage, nonunion, and large bone loss. There will be more exposed stent nails after bone transport.

[0003] Medical staff need to perform dressing changes and care for external fixators and traction pins every day, including covering the pins with sterile dressings and bandaging. Because the bandages need to pass through various irregular and narrow needle channels, the bandaging process is very time-consuming, about 30 minutes on average, and the work efficiency is low. The tightness of the bandage is not easy to adjust, and the skin feels stuffy after bandaging, with poor air permeability and an increased chance of skin rashes. If adhesive tape is used, the wet dressing will not stick steadily, and long-term use of adhesive tape fixation can easily cause skin allergies.

[0004] The external fixator treatment cycle is long, taking about 1 to 2 years on average. During the home stay, it is very difficult and time-consuming for patients to self-care for the nail site dressings, and the nail site contamination rate is high, which is not conducive to home care of the external fixator nail sites and rehabilitation of the affected limb.

[0005] For this reason, a positioning device for fixing the traction nail dressing is urgently needed. Utility Model Content

[0035] Reference Figures 1 to 4 The fracture traction nail dressing positioning device of the utility model is made into the following embodiments:

[0036] The fracture traction nail dressing positioning device comprises a first clamping member 100 , a second clamping member 200 , and a clamping member 300 .

[0037] A first abutting portion 110 is disposed at the bottom of the first clamp 100 , and the first abutting portion 110 extends outward.

[0038] The side wall of the first clamping member 100 is provided with a first clamping groove 120 penetrating in the up-down direction.

[0039] The first abutting portion 110 extends away from an area directly facing the first clamping groove 120 .

[0040] A second abutting portion 210 is disposed at the bottom of the second clamping member 200 , and the second abutting portion 210 extends outward.

[0041] The side wall of the second clamping member 200 is provided with a second clamping groove 220 penetrating in the up-down direction.

[0042] The second abutting portion 210 extends away from an area directly facing the second clamping groove 220 .

[0043] The clamping member 300 connects the first clamping member 100 and the second clamping member 200 , and the clamping member 300 can drive the first clamping member 100 and the second clamping member 200 to move closer to each other or away from each other.

[0044] The first clamping groove 120 and the second clamping groove 220 are disposed opposite to each other.

[0045] When the first clamping member 100 and the second clamping member 200 are close to each other, the first clamping groove 120 and the second clamping groove 220 are closed to form a clamping space 11 , and the clamping space 11 is used to clamp the fracture traction nail 10 .

[0046] When the first clamping member 100 and the second clamping member 200 move away from each other, the first clamping groove 120 and the second clamping groove 220 move away from each other, and the first abutting portion 110 and the second abutting portion 210 move away from each other, forming an escape channel 12 for the fracture traction nail 10 to enter and exit the clamping space 11 .

[0047] When it is necessary to fix the dressing at the nail opening of the fracture traction nail, the first clamping member 100 and the second clamping member 200 are driven away by the clamping member 300 to form an avoidance channel 12 between the first clamping member 100 and the second clamping member 200, and then the fracture traction nail 10 is made to enter between the first clamping groove 120 and the second clamping groove 220 along the avoidance channel 12, and then the clamping member 300 drives the first clamping member 100 and the second clamping member 200 to approach so that the fracture traction nail 10 is clamped in the clamping space 11, so that the first abutting portion 110 and the second abutting portion 210 can abut against the dressing at the nail opening of the fracture traction nail 10, so that the dressing is fixed at the nail opening.

[0048] Then, the first clamping member 100 is driven away from the second clamping member 200 by the clamping member 300, and the positions of the first clamping member 100 and the second clamping member 200 are adjusted along the axial direction of the fracture traction nail 10, so as to appropriately adjust the positions of the first abutting portion 110 and the second abutting portion 210 to avoid crushing the user's wound.

[0049] When the dressing on the nail opening of the fracture traction nail 10 needs to be removed, the first clamping member 100 is driven away from the second clamping member 200 by the clamping member 300 to form an escape channel 12 between the first clamping member 100 and the second clamping member 200, and then the fracture traction nail 10 is removed along the escape channel 12.

[0050] The first abutting portion 110 extends within a range that avoids the area directly facing the first clamping groove 120 , and the second abutting portion 210 extends within a range that avoids the area directly facing the second clamping groove 220 .

[0051] The first abutting portion 110 and the second abutting portion 210 are prevented from blocking the fracture traction nail 10 from entering and exiting the clamping space 11, and the first clamping member 100 and the second clamping member 200 are prevented from hitting the fracture traction nail 10 and causing discomfort to the patient.

[0052] Therefore, the fracture traction nail dressing positioning device is used to fix the nail mouth dressing, which is easy to operate and easy to care for.

[0053] In some embodiments, the clamping member 300 includes a first movable part and a second movable part, the first movable part and the second movable part are slidably connected, the first movable part and the second movable part are respectively connected to the first clamping member 100 and the second clamping member 200, and the first movable part and the second movable part slide closer to each other or farther away from each other to make the first clamping member 100 and the second clamping member 200 closer to or farther away from each other, and the clamping member 300 can also be provided with a locking member connecting the first movable part and the second movable part. After the first movable part and the second movable part approach each other, the locking member locks the first movable part and the second movable part so that the first clamping member 100 and the second clamping member 200 clamp the fracture traction nail 10.

[0054] In some embodiments, the clamping member 300 includes a first hinge portion 310 , a second hinge portion 320 , and an elastic member.

[0055] The first hinged portion 310 is hinged to the second hinged portion 320, the first hinged portion 310 is connected to the first clamping member 100, the second hinged portion 320 is connected to the second clamping member 200, and the elastic member is arranged between the first hinged portion 310 and the second hinged portion 320. The elastic force of the elastic member drives the first hinged portion 310 and the second hinged portion 320 to approach each other, so that the first clamping member 100 is close to the second clamping member 200.

[0056] The first hinged portion 310 is driven close to the second hinged portion 320 by the elastic force of the elastic member. Under normal circumstances, the first clamping member 100 is close to the second clamping member 200 so that a clamping space 11 is formed between the first clamping groove 120 and the second clamping groove 220 to clamp the fracture traction nail 10, thereby preventing the first clamping member 100 and the second clamping member 200 from loosening and causing the nail mouth dressing of the fracture traction nail 10 to loosen.

[0057] In some embodiments, the first hinged portion 310 is provided with a first handle 311 extending above the first abutting portion 110 , and the second hinged portion 320 is provided with a second handle 321 extending above the second abutting portion 210 .

[0058] The user operates the first handle 311 and the second handle 321 to open the first hinged portion 310 and the second hinged portion 320, and can determine the relative positions of the first abutting portion 110 and the second abutting portion 210, and the relative positions of the first clamping member 100 and the second clamping member 200 according to the positions of the first handle 311 and the second handle 321, so that the user can loosen or clamp the fracture traction nail 10 after operation.

[0059] In some embodiments, a notch 13 is disposed between the first abutting portion 110 and the second abutting portion 210 , and an axis of a hinged portion between the first hinged portion 310 and the second hinged portion 320 is located above the notch 13 .

[0060] When the first hinged portion 310 rotates relative to the second hinged portion 320, an escape channel 12 is left on one side of the first clamping groove 120 and the second clamping groove 220, and the escape channel 12 is used for the fracture traction nail 10 to enter and exit, and the other side of the first clamping groove 120 and the second clamping groove 220 is a notch 13. When the first abutting portion 110 rotates relative to the second abutting portion 210, the notch 13 can provide space to avoid the first abutting portion 110 from interfering with the second abutting portion 210.

[0061] In some embodiments, a soft gasket is disposed at the bottom of the first abutting portion 110 , and a soft gasket is disposed at the bottom of the second abutting portion 210 .

[0062] The bottom of the first abutting portion 110 and the second abutting portion 210 compresses the nail mouth dressing of the fracture traction nail 10 and the patient's skin through the soft gasket, and the soft gasket can reduce the pressure of the first abutting portion 110 and the second abutting portion 210 on the patient.

[0063] In some embodiments, the first abutment portion 110 gradually tilts downward in a direction away from the first clamping groove 120, and the second abutment portion 210 gradually tilts downward in a direction away from the second clamping groove 220. A soft gasket is provided at the bottom edge of the first abutment portion 110, and a soft gasket is provided at the bottom edge of the second abutment portion 210.

[0064] Since the first abutting portion 110 and the second abutting portion 210 form a funnel-shaped structure that is smaller at the top and larger at the bottom, when the first abutting portion 110 and the second abutting portion 210 press the dressing and the nail position, a cavity is formed between the first abutting portion 110 and the second abutting portion 210 to avoid squeezing the patient's wound position, and the soft gasket at the bottom edge is used to squeeze the dressing to reduce side leakage of the dressing.

[0065] In some embodiments, the clamping space 11 is circular.

[0066] This helps to increase the area of ​​the first clamping groove 120 and the second clamping groove 220 abutting against the outer wall of the fracture traction nail 10, and when clamping the fracture traction nail 10, it prevents the first clamping member 100 and the second clamping member 200 from shaking relative to the fracture traction nail 10 to cause discomfort to the patient or loosening of the dressing.

[0067] In some embodiments, the width of the avoidance channel 12 is greater than the diameter of the clamping space 11 .

[0068] This allows the fracture traction nail 10 to enter and exit the clamping space 11 through the avoidance channel 12 .

[0069] In some embodiments, the first abutting portion 110 is provided with an observation hole penetrating along the up-down direction, and the second abutting portion 210 is provided with an observation hole penetrating along the up-down direction.

[0070] Medical staff can check the condition of the dressing through the observation hole so as to change the dressing in time.

[0071] In some embodiments, the first abutting portion 110 and the second abutting portion 210 are both transparent members.

[0072] Medical personnel can observe the use of the dressing or the bleeding of the patient through the first abutting portion 110 and the second abutting portion 210 so as to provide timely treatment.

[0073] Specifically, refer to Figures 1 to 4 As shown, the fracture traction nail dressing positioning device includes a first clamping member 100 , a second clamping member 200 , and a clamping member 300 .

[0074] A first abutting portion 110 is disposed at the bottom of the first clamp 100 , and the first abutting portion 110 extends outward.

[0075] The side wall of the first clamping member 100 is provided with a first clamping groove 120 penetrating in the up-down direction.

[0076] The outwardly extending range of the first abutting portion 110 avoids the area directly facing the first clamping groove 120 , and the first clamping groove 120 is an arc groove.

[0077] The first abutting portion 110 gradually tilts downward in a direction away from the first clamping groove 120 , and a soft gasket is disposed on an edge of the bottom of the first abutting portion 110 , and the soft gasket is a soft silicone pad.

[0078] The first contact portion 110 is provided with an observation hole penetrating vertically.

[0079] The first abutting portion 110 is provided with a reinforcing rib, and the reinforcing rib extends along an extending direction of the first abutting portion 110 .

[0080] A second abutting portion 210 is disposed at the bottom of the second clamping member 200 , and the second abutting portion 210 extends outward.

[0081] The side wall of the second clamping member 200 is provided with a second clamping groove 220 penetrating in the up-down direction.

[0082] The outwardly extending range of the second abutting portion 210 avoids the area directly facing the second clamping groove 220 , and the second clamping groove 220 is an arc groove.

[0083] The second abutting portion 210 gradually tilts downward in a direction away from the second clamping groove 220 , and a soft gasket is disposed at an edge of the bottom of the second abutting portion 210 , and the soft gasket is a soft silicone pad.

[0084] The second contact portion 210 is provided with an observation hole penetrating in the up-down direction.

[0085] The second abutting portion 210 is provided with a reinforcing rib, and the reinforcing rib extends along an extending direction of the second abutting portion 210 .

[0086] A notch 13 is disposed between the first abutting portion 110 and the second abutting portion 210 .

[0087] The first abutting portion 110 and the second abutting portion 210 are both made of transparent plastic.

[0088] The clamping member 300 is a clip with a spring, and the clamping member 300 includes a first hinged portion 310, a second hinged portion 320 and an elastic member. The first hinged portion 310 is connected to the first clamping member 100, the second hinged portion 320 is connected to the second clamping member 200, and the notch of the first clamping groove 120 is arranged opposite to the notch of the second clamping groove 220.
