Description

A kind of X-ray photographic, perspective use fixing device for extremity

Technical field

The utility model relates to field of medical device, and in particular to it is a kind of medical treatment perspective use fixing device for extremity.

Background technique

X-ray photographic, perspective are that a kind of patient with bone fracture is used to fix when carrying out X-ray photographic, perspective with fixing device for extremity With the medical device of limit limbs posture.In patient with bone fracture operation, needs to carry out X-ray photographic in time, fluoroscopic observation bone, closes Form, the line of force of section, the information such as direction, length of inner implantation material are to ensure that operation is gone on smoothly；In X-ray photographic, had an X-rayed Cheng Zhong, patient needs to show various special postures to meet the photographing request of medical image, but operative site in patients surgery Local anaesthesia has been carried out, correct posture can not be put and adjust out.In practice, it is done by medical worker's books or various kinds object Backer limits the body part of patient, but effect is undesirable；Especially for needing to furnish special shooting posture and shooting angle In the case of degree, often medical worker can in person with hand steered limbs, limbs are applied with external force to form various perspective positions, but cure Business personnel, which are chronically exposed under X-ray photographic, has very big radiation hazradial bundle for example carcinogenic etc. body；In addition can not by X-ray photographic, Perspective accurately obtains the information such as direction, the length of inner implantation material, so that doctor can be accurately to the direction of inner implantation material It is corrected with length, doctor is usually by rule of thumb and to feel, even occurs sometimes to the length of inner implantation material repeatedly, is more On the one hand secondary correction increases the workload of doctor, increases the psychological pressure of patient, more seriously increases patient by x-ray Photography, the amount of radiation having an X-rayed, to cause damages to patient body.However existing technology is also not yet in effect solves the above problems, Such as 202515676 U of Chinese patent Granted publication Authorization Notice No. CN discloses a kind of x-ray on November 07th, 2012 and takes the photograph Shadow, perspective arm fixing device, it includes supporting structure, and the supporting structure is in cuboid-type bracket, the cuboid-type On bracket plane be equipped at least two grooves, the groove be it is U-shaped, groove slot bottom be arcuation or straight panel shape, the groove is with length Cube type bracket bilateral symmetry center line is symmetrical.Its working principle is that being equipped at least two using plane on cuboid-type bracket Groove a or that suitable position is selected more than or less than patient, arm is placed in a groove, is held using cuboid-type bracket Arm meets photographing request by the posture that the requirement of medical worker adjusts oneself；But cuboid-type branch is utilized in the Patent Case Frame torr lives to place arm in a groove, and the posture that arm is put is fixed by groove, limits the ineffective of posture, only Fixed function is played, often can not effectively be limited in the case of complicated shooting posture and shooting angle especially for needing to furnish The ornaments posture and angle of limbs, while direction and the length number of inner implantation material can not be accurately obtained by X-ray photographic, perspective According to.

Utility model content

The utility model mainly solves existing X-ray photographic, perspective, and with arm fixing device to fix limit effect poor, and can not The technical issues of precisely obtaining the information such as direction and the length of limbs inner implantation material by X-ray photographic, perspective；A kind of X is provided Line photography, perspective realize the x-ray by perspective board, the combined innovation of gag lever post and mesh coordinate structure with fixing device for extremity Photography, perspective with fixing device for extremity have structure it is simple, using it is easy, limbs are fixed with good limit effect, and X can be passed through The characteristics of line photography, perspective obtain direction and the length exact value of inner implantation material.

The technical scheme in the invention for solving the above technical problem are as follows: a kind of X-ray photographic, perspective fix dress with limbs It sets, it includes perspective board and limited post, and the perspective board and limited post are all made of nonmetallic materials and are made, and the perspective board is in length Cube structure, perspective board top are equipped with limit hole, and limited post is inserted in the limit hole, and the perspective board bottom is equipped with coordinate Grid.This X-ray photographic, perspective use fixing device for extremity, using the limited post plugged in limit hole to limbs apply external force with Various perspective positions are formed, while can learn direction and the length of limbs inner implantation material when X-ray photographic, perspective by mesh coordinate Degree evidence.

Preferably, being covered with limit hole at the top of the perspective board, the limit hole transverse and longitudinal uniformly interlocks successively in proportion Distribution.The advantage is that can furnish needs according to position, and limited post is planted in each limit hole, and the limited post produces limbs Raw external force, it is easy to be reliable to form required perspective position.

Preferably, the limited post is cylindrical body, limited post can be divided into four kinds of different specifications of length.Pass through different rule The different arrangement in limit hole of the limited post of lattice is planted, and can meet the needs of limbs various position supports, such as carpal Neutral position, ruler deviation, oar deviation, ankle-joint, kneed side stress position etc..

Preferably, the coordinate grid is embedded in perspective board bottom, coordinate grid is made of metal material, by metal Grid lines transverse and longitudinal is in staggeredly uniformly matts distribution of shapes, and grid spacing is equal, forms coordinate grid.It the advantage is that metal Material is shown as black projection under X-ray photographic, perspective in perspective screen；In X-ray photographic, perspective, limbs are implanted into fixation Material is projected on coordinate grid simultaneously, can calculate its length according to the projection that limbs shown on grid are implanted into fixed material Exact value is spent, doctor is facilitated accurately to be adjusted to the fixation material that limbs are implanted into time, doctor's workload is reduced, improves Procedure efficiency.

With the above mentioned technical proposal compared with prior art, the benefit of the utility model is the utility model: this Kind X-ray photographic, perspective fixing device for extremity, utilize the limited post of different size row different in the limit hole on perspective board Column are planted, while limited post generates external force to limbs, easy to be reliable to form required perspective position；In addition X-ray photographic, When perspective, the coordinate grid being equipped with by perspective board bottom can calculate the length that limbs are implanted into fixed material, facilitate doctor The fixation material that limbs are implanted into accurately is adjusted in time, doctor's workload is reduced, improves procedure efficiency.
