Description

A kind of Kirschner wire protection traction cap

Technical field

The present invention relates to orthopaedic technique fields, and in particular to a kind of Kirschner wire protection traction cap.

Background technique

In Orthopedic Clinical medical treatment, limb fracture, Joint shift reset or when treatment of reconstructive operation, usually use kirschner Needle has the following deficiencies: the kirschner for staying in outer body when some small bones such as hand, Minor articulus use Kirschner wire fixation Needle is easily trapped into tumor, is not drawn out easily after patient affected part soft tissue swelling, and currently used method is will to expose Outer part bending, but in bending process will cause Kirschner wire deformation, or even integrated part is made to deform displacement, cause Operative failure, and the Kirschner wire of bending in convalescence Kirschner wire, by scraping collision, or by clothing, bedding etc., take out of by other articles, makes At interior fixed displacement, lead to operative failure；Exposed Kirschner wire can also bring psychological fear to some patientss, influence patient Normal life.

It at present there are also simple Kirschner needle protective cap, is supported using silica gel, is buckled in Kirschner wire exposed junction, be one end It is set as the cavity of opening, the head of Kirschner wire is put into cavity, is had the disadvantage in that the chamber of Kirschner wire insertion protective cap It when internal, needs to be capable of clamping with tweezers, exert a force, the part that Kirschner wire is exposed is short, it has not been convenient to use other tools, it has not been convenient to Protective cap is applied to the end of Kirschner wire, installs and has a certain distance between rear protective cap and skin, is easy by extension, and This protective cap does not have bite force to Kirschner wire, is easy to fall off, and does not have corresponding protective effect.

Summary of the invention

To overcome the deficiency, the purpose of the present invention is to provide a kind of Kirschner wires to protect traction cap.

The technical solution adopted by the present invention to solve the technical problems is: a kind of Kirschner wire protection traction cap, including cap sheet Body, locking nut, the cap ontology include drawing head, clamping head, and the cap ontology is externally provided with locking nut, the drawing head Lower end is fixedly connected with the upper end of clamping head, is equipped in the clamping head and is set needle cavity body, and clamping head outer wall is set as part pyramid like configuration, It is become larger from the upper end of clamping head to lower end outer diameter, the inner wall of clamping head is cylindrical surface structure, the outer wall of drawing head and clamping Head outer wall smooth transition, drawing head, clamping head outer wall are equipped with external screw thread, match with the internal screw thread of locking nut, the clamping Head wall is equipped with strip through-hole, and strip through-hole is arranged along the central axial direction of clamping head.

Specifically, the upper surface of the drawing head is set as globoidal structure.

Specifically, the drawing head is equipped with reserved towing pad.

Specifically, the clamping head includes shell, buffer layer, is equipped with buffer layer on the inside of the shell of the clamping head.

Specifically, the drawing head is entity structure, and the shell of drawing head and clamping head is structure as a whole.

Specifically, the buffer layer is high temperature resistant elastic material.

Specifically, the buffer layer is medical cotton yarn layer.

Specifically, the shell of the drawing head and clamping head is stainless steel material or medical rigid plastics.

Specifically, the cross section of the strip through-hole is fan-shaped.

The invention has the following advantages: the present invention facilitates the end that protective cap is applied to Kirschner wire, rear cap is installed Gap is small between ontology and skin, it is not easy to by extension, apply bite force to clamping head by locking nut, avoid external force Lower cap ontology falls off；Drawing head can be fixedly connected with fixed frame, hitch frame, traction rope etc., carry out associated treatment, behaviour to patient Facilitate.

Detailed description of the invention

Fig. 1 is the structural diagram of the present invention.

Fig. 2 is cross-sectional view at A-A of the invention.

Fig. 3 is cap body construction schematic diagram of the invention.

1 drawing head in figure, 11 reserved towing pads, 2 clamping heads, 21 external screw threads, 22 shells, 23 buffer layers, 3 strip through-holes, 4 Locking nut, 41 anti-skid chequers, 5 set needle cavity body.

Specific embodiment

In conjunction with the accompanying drawings, the present invention is further explained in detail.

According to Fig. 1, Fig. 2, a kind of Kirschner wire protection traction cap shown in Fig. 3, including cap ontology, locking nut 4, the cap Ontology includes drawing head 1, clamping head 2, and the cap ontology is externally provided with locking nut 4, the lower end of the drawing head 1 and clamping head 2 Upper end be fixedly connected, be equipped in the clamping head 2 and set needle cavity body 5,2 outer wall of clamping head is set as part pyramid like configuration, circular cone half Angle is 2-5 °, is become larger from the upper end of clamping head 2 to lower end outer diameter, and the inner wall of clamping head 2 is cylindrical surface structure, drawing head 1 Outer wall and 2 outer wall of clamping head seamlessly transit, drawing head 1,2 outer wall of clamping head be equipped with external screw thread 21, the interior spiral shell with locking nut 4 Line matches, and 2 wall of clamping head is equipped with strip through-hole 3, and strip through-hole 3 is arranged along the central axial direction of clamping head 2, when When needing to protect Kirschner wire exposed junction, 4 whiz clamping head 2 of locking nut is placed on 1 position of drawing head, then that Kirschner wire is exposed End is caught in out of strip through-hole 3 sets in needle cavity body 5, is rotated down locking nut 4, since clamping head 2 is part pyramid like configuration, downwards When rotating locknut cap 4, since locking nut gradually reduces clamping head 2, clamping head 2 can be generated inwardly and squeeze bite force, will Kirschner wire, which is engaged in, to be set in needle cavity body 5, will not be hit fall off easily in this way, is also convenient for for cap ontology being completely encapsulated in outside Kirschner wire Reveal end, it is small with illing skin gap.

Specifically, the upper surface of the drawing head 1 is set as globoidal structure.

Specifically, the drawing head 1 is equipped with reserved towing pad 11, fixed or when drawing Kirschner wire when needing, can be with It is fixed by connector and reserved towing pad 11 with fixed frame or hitch frame, traction rope etc., it is fixed or draws, grasp Make convenient and simple.

Specifically, the clamping head 2 includes shell 22, buffer layer 23, is equipped with buffering on the inside of the shell 33 of the clamping head 2 Layer 23.

Specifically, the drawing head 1 is entity structure, and drawing head 1 and the shell of clamping head 2 are structure as a whole.

Specifically, the buffer layer 23 is high temperature resistant elastic material.

Specifically, the buffer layer 23 is medical cotton yarn layer.

Specifically, the shell of the drawing head 1 and clamping head 2 is stainless steel material or medical rigid plastics.

Specifically, the cross section of the strip through-hole 3 is fan-shaped, facilitates Kirschner wire to be put into and sets in needle cavity body.

The present invention is not limited to the embodiment, anyone should learn that the structure made under the inspiration of the present invention becomes Change, the technical schemes that are same or similar to the present invention are fallen within the scope of protection of the present invention.
