Abstract
The utility model discloses a prizing and poking repositor for radius head fracture, composed of a restoring tongue (5), a prizing and poking rod (2) and a handle (3). The restoring tongue (5) is positioned at the anterior part of the repositor, and an arc transition section (1) is arranged between the restoring tongue and the prizing and poking rod (2). The handle (3) is connected with the back end of the prizing and poking rod (2). Compared with the existing therapy method, the utility model has the advantages that firstly, the restoring tongue adopts insensitivity, the vascular nerve is not easily damaged when the restoring tongue enters the hypodermis, and the use is safe; secondly, the restoring tongue is tabular, an arc transition section is arranged between the restoring tongue and the prizing and poking rod, the prizing and poking strength is large, the contact surface is big, and the fractured end is not easy to break; thirdly, the handle is tabular, skidproof print is arranged on the handle, not only up-down prizing and poking but also rotary prizing and poking can be realized, and the prizing and poking direction is omnidirection; fourthly, the planes of the handle and the head are identical, which is convenient for controlling the fracture prizing and poking direction.
Description
Affiliated technical field
This utility model belongs to medical instruments field, relates generally to a kind of fracture of capitulum radii percutaneous reduction by leverage device that is used for the reduction of the fracture.
Background technology
At present, the Therapeutic Method that is used for fracture of capitulum radii mainly contains: methods such as operative treatment, maneuver closed reduction, percutaneous draw point percutaneous reduction by leverage.Operative treatment adopts open reduction or capitulum radii excision usually.Because of the special anatomy relationship in capitulum radii place, operation is complicated, the easy damaged of performing the operation simultaneously radial nerve, and postoperative effect is poor, and easily forms the elbow joint myositis ossificans, causes elbow joint to bend and stretch dysfunction; Simple manual reduction is applicable to that mainly the displacement fracture degree is less, and intercalation is than the lighter, and is inapplicable for the intercalation severe patient; Percutaneous draw point percutaneous reduction by leverage is applicable to the intercalation fracture compound comminuted, but because of it is not a specific purpose tool, operation inconvenience, the dynamics that resets is difficult for grasping.
Summary of the invention
The purpose of this utility model provides a kind of fracture of capitulum radii percutaneous reduction by leverage device simple in structure, safe in utilization.
The purpose of this utility model can adopt following technical scheme to realize: it mainly is made of the tongue that resets, sled driving lever and handle, and the tongue that resets is positioned at the front end of positor, its with the sled driving lever between have an arc-shaped transition section, handle is connected the rear end of prizing driving lever.
Described handle is a flat, and is consistent with the plane of the tongue that resets.
Be provided with anti-skidding stricture of vagina on the surface of handle.
This utility model is mainly used in fracture of capitulum radii, and it has compared following advantage with existing Therapeutic Method: the tongue that 1, resets adopts passivity, is difficult for the injured blood vessel nerve when entering subcutaneous tissue, and is safe in utilization; 2, the tongue that resets is a flat, has an arc-shaped transition section between itself and the sled driving lever, and sled is dialled great efforts, and contact surface is big, is difficult for the broken fracture end of sled; 3, handle is flat, on anti-skidding stricture of vagina is arranged, not only can prize up and down when sled is dialled and dial also rotatable sled and dial, sled group direction is comprehensive; 4, handle is consistent with header planes, is convenient to grasp the fracture sled and dials direction.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Vertical view when accompanying drawing 2 is flat calabash shape for handle among Fig. 1
Accompanying drawing 3 is the vertical view when handle is for ellipse among Fig. 1.
Among the figure: 1, arc-shaped transition section, 2, the sled driving lever, 3, handle, 4, anti-skidding stricture of vagina, 5, tongue resets.
The specific embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
As shown in Figure 1, described positor mainly is made of the flat tongue 5 that resets, sled driving lever 2, handle 3, and resetting has an arc-shaped transition section 1 between tongue 5 and the sled driving lever 2, and handle is connected the rear end of sled driving lever 2.The tongue 5 that resets is part in the intrusion human body body with arc-shaped transition section 1, and tongue 5 rear ends that reset are connected to arc-shaped transition with arc-shaped transition section 1 and are connected, and the feasible tongue 5 that resets is pair arcs continuously with arc-shaped transition section 1, is used to insert fracture end, plays the percutaneous reduction by leverage effect;
Handle is a flat, and is consistent with the plane of the tongue that resets, and its shape can be various, and handle as shown in Figure 2 is the calabash shape, and handle shown in Figure 3 is oval.The surface of handle is provided with anti-skidding stricture of vagina 4 and is provided with anti-skidding stricture of vagina, can vertically prize and dial, and can rotate sled again and dial.
The percutaneous reduction by leverage method: adopt brachial plexus block anesthesia, after coming into force, the patient lies on the back on operating-table, art district routine disinfection drape.One assistant draws patient's upper arm, and another assistant draws patient's forearm, keeps suffering from the position, cubitus varus, makes the broadening of humeroradial joint gap, keeps the elbow joint semi-flexed position.Fracture of capitulum radii position and direction of displacement are found out, under perspective in patient's left hand thumb extruding capitulum radii outside, entry point is selected in the below outside elbow, sting a skin incision with sharp knife, the right hand is held the positor tongue that will reset and is thrust the skin subcutaneous tissue, until fracture gap, utilize folding end far away to be the strong point, raise, press down or rotary handle, dial capitulum radii by the tongue sled that resets, the contrary displacement fracture direction of left hand thumb is pushed capitulum radii simultaneously, the assistant rotates forearm, makes the reduction of the fracture.As fracture angulation deformity is arranged, available positor props up capitulum radii and pushes, and is corrected to the angle.Under perspective, after reduction of the fracture satisfaction, pull out positor, bend elbow 90 degree.The aseptic dressing wrapping.Also can be in elbow in the wrong 90 degree positions, one piece of osseous pin is penetrated capitulum radii along the radius direction and fracture end far away is fixed behind the humerus ectocondyle.
