Description

Technical Field

[0001] The utility model relates to the technical field of calcaneal traction, in particular to a calcaneal traction fixing device. Background Art

[0002] The role of calcaneal traction can be summarized into two major roles in clinical practice, namely maintaining fracture reduction and relieving pain. In orthopedic clinical practice, calcaneal traction is generally used for tibia and fibula fractures for preoperative maintenance of reduction or symptomatic treatment to relieve pain. This technology is of great significance for preoperative fracture reduction, reducing the difficulty of reduction during surgery, and reducing sequelae such as poor fracture healing, malformation healing and poor surgical reduction, and is for surgical preparation. When fixing the patient's calcaneus, a traction fixation pin is usually passed through the calcaneus from the inside to the outside through the midpoint of the line connecting the tip of the ankle and the posterior and inferior edge of the heel, and then a traction frame is installed on both sides of the traction fixation pin, and appropriate weight is added to the traction frame for traction. The traction force is maintained by hanging a certain weight of a weight or sandbag.

[0003] In the prior art, C-type disinfection patches pasted on the traction bow are sleeved on both ends of the traction fixation needle close to the patient's root bone, and the two C-type disinfection patches are used to squeeze the puncture hole near the patient's root bone to disinfect the wound and prevent infection by bacteria. The C-type disinfection patch will be contaminated after long-term contact with the patient's puncture hole, and the disinfection effect will be weakened. In order to facilitate the treatment of the patient, the C-type disinfection patch needs to be replaced regularly, but this pasting and fixing method is not convenient for replacing the C-type disinfection patch.

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0044] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0046] When using the calcaneal traction and fixation device, first use the fixing needle to puncture the patient's calcaneus. After the puncture is successful, the traction bow is connected to the fixing needle through the hook at the end, so that the traction bow and the fixing needle maintain a detachable connection. Then, the traction ring set in the middle of the traction bow is connected to the external traction device and the traction force is set to traction and fix the patient's calcaneus.

[0047] In the related art, the C-type disinfection patch in the disinfection mechanism of the calcaneal traction fixation device is not easy to replace. Generally, the C-type disinfection patch can only be removed by tearing the adhesive on the C-type disinfection patch to separate the C-type disinfection patch from the traction bow, and then pulling the C-type disinfection patch off the fixing pin through the notch of the C-type disinfection patch. During use, the C-type disinfection patch cannot be replaced quickly and conveniently.

[0048] In order to solve the problems in the related art to a certain extent, an embodiment of the present application provides a calcaneal traction fixation device. When the C-type disinfection cotton 56 needs to be replaced, it is only necessary to manually pull the C-type disinfection cotton 56 attached to the puncture hole so that the C-type disinfection cotton 56 is torn off the fixing needle through the notch. Through the elastic force of the spring 53, the unused C-type disinfection cotton 56 that is in contact with the old C-type disinfection cotton 56 replaces the old C-type disinfection cotton 56 and is attached to the patient's puncture hole, thereby realizing the replacement of the C-type disinfection cotton 56 more conveniently and quickly.

[0049] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0050] Combination Figure 1-Figure 6 The embodiment of the present application provides a calcaneal traction and fixation device, including a traction bow 1, a traction ring 2 arranged on the outer wall of the middle part of the traction bow 1, and a fixing needle 3 movably connected to the two ends of the traction bow 1; a disinfection component 5 is arranged on the fixing needle 3, and the disinfection component 5 includes: a groove body 51 is respectively sleeved on the two ends of the fixing needle 3; a slide groove 52 is opened at one end of the groove body 51; a spring 53 is arranged in the slide groove 52; a slider 54 is slidably connected in the slide groove 52 and connected to the spring 53; a strip through hole 57 is opened on the inner wall of the groove body 51, connected to the slide groove 52, and one end of the slider 54 is slidably connected to the strip through hole 57; a ring body 55 is slidably connected to the outer wall of the fixing needle 3 and connected to the slider 54; a C-type disinfection cotton 56 is superimposed on the surface of the ring body 55 and is slidably connected to the fixing needle 3.

[0051] The groove bodies 51 are sleeved on both ends of the fixing needle 3 relative to the root bones of the patient, and the sliding grooves 52 are respectively opened on the opposite surfaces of the two groove bodies 51 . When the C-type disinfection cotton 56 needs to be replaced, a new C-type disinfection cotton 56 close to the old C-type disinfection cotton 56 is pressed to leave some gaps between the two C-type disinfection cottons 56, and the old C-type disinfection cotton that fits the patient's root bone puncture hole is pulled to tear the old C-type disinfection cotton off the fixed needle 3 through the notch, and the new C-type disinfection cotton 56 is released. The spring 53 recovers its deformation and pushes the slider 54 to slide in the slide groove 52, so that the slide groove 52 drives the ring body 55 to slide in the groove of the groove body 51, and the ring body 55 pushes the superimposed C-type disinfection cotton 56 to move on the fixed needle 3 toward the opening of the groove body 51. The elastic force of the spring 53 recovers its deformation to make the unused C-type disinfection cotton 56 that fits the old C-type disinfection cotton 56 fit the patient's puncture hole, thereby realizing the replacement of the C-type disinfection cotton 56 more conveniently and quickly.

[0052] Specifically, the disinfectant on the C-type disinfection cotton 56 can be 75% alcohol, iodine, 0.025% iodine tincture, chlorhexidine, etc. The material of the C-type disinfection cotton 56 is sterile cotton with a certain adsorption capacity.

[0053] In some embodiments, the slider 54 is composed of two parts, and the cross-section of the rod body slidably connected to the bar-shaped through hole 57 is smaller than the cross-section of the circular ring slidably connected to the sliding groove 52 .

[0054] The size of the strip-shaped through hole 57 is reduced to prevent the C-shaped sterilizing cotton 56 from being stuck in the strip-shaped through hole 57 and affecting its movement on the fixing needle 3 .

[0055] In some embodiments, two slide grooves 52 are symmetrically provided on one end surface of the slot body 51 , and a spring 53 and a slider 54 connected to the spring 53 are disposed in each of the two slide grooves 52 .

[0056] This allows the ring body 55 to slide more smoothly in the groove body 51 , thereby increasing the squeezing force on the C-shaped sterilizing cotton 56 .

[0057] In some embodiments, the two slide grooves 52 are each provided with an axle body 6 penetrating the circular ring portion of the slider 54 , and the spring 53 is sleeved on the axle body 6 .

[0058] The spring 53 can be extended and retracted in the slide groove 52 more smoothly, thereby increasing the stability of the slider 54 when sliding in the slide groove 52 .

[0059] In some embodiments, waterproof padding paper 8 is provided between the C-shaped sterilizing cotton 56 stacked in pairs, and the waterproof padding paper 8 is sleeved on the fixing needle 3 .

[0060] This prevents the user from contaminating the new C-type disinfection cotton 56 when pressing the new C-type disinfection cotton 56 that fits the old C-type disinfection cotton 56, and also prevents the old C-type disinfection cotton 56 from contaminating the new C-type disinfection cotton 56 during use. When replacing the C-type disinfection cotton 56, just tear off the waterproof padding paper 8 that blocks the new C-type disinfection cotton 56.

[0061] In some embodiments, the C-shaped sterilizing cotton 56 disposed in the groove body 51 is in an elastically compressed state.

[0062] Add C-type disinfection cotton 56 to disinfect the surface of the patient's root bone puncture hole.

[0063] In some embodiments, a sealing ring 7 is disposed in the hole of the groove body 51 through which the fixing needle 3 passes.

[0064] The friction force when the groove body 51 is sleeved on the fixing needle 3 is increased, and the stability of the fixing between the groove body 51 and the surface of the fixing needle 3 is improved.

[0065] In some embodiments, the groove body 51 , the slider 54 , the shaft body 6 and the ring body 55 are all made of medical grade materials.

[0066] The hygiene of the groove body 51, the slider 54, the shaft body 6 and the ring body 55 is increased, and the probability of infection of the root bone puncture hole of the patient is reduced.
