Abstract
The utility model discloses a novel trephine which comprises a trephine rod (1), trephine teeth (2) and a handle (3), wherein the trephine teeth (2) are arranged at one end of the trephine rod (1); a connector (4) is arranged at the other end of the trephine rod (1), and a connecting groove (6) matched with the connector (4) is formed on the handle (3); and the junction of any two of the trephine teeth (2) is circular arc-shaped. The novel trephine has the advantages that the trephine teeth are not easy to fracture, and the service life is long; and moreover, the malleability of the trephine teeth can be improved, and a doctor can know the length of the trephine inserted into a human body clearly during an operation, so that the operation risk is effectively lowered.
Description
Technical field
This utility model relates to the novel trepan of a kind of trepan, particularly a kind of long service life.
Background technology
When the treatment intervertebral disc prolapse; Under the situation of prolapse of intervertebral disc; In order to make the service aisle spinal column chamber of arriving safe and sound, the part that needs to use the trepan rotation to remove the outgrowth sclerotin of little joint far-end and part upper joint projection enlarges intervertebral foramina, makes the service aisle arrival spinal column chamber of spinal endoscopes; Use operating theater instruments to extract the nucleus pulposus that hernia goes out, reach the purpose of treatment intervertebral disc prolapse.
The sawtooth of trepan all adopts the structure shown in Fig. 6 in the market, between tooth and the tooth shape in an angle, in use the doctor finds; Traditional trepan is short service life, and sawtooth is easy to from the root fracture behind life-time service, and the tooth that falls down so will drop in human body in case sawtooth takes place to rupture; Can bring life danger to patient like this; The doctor also needs spended time that the tooth of fracture is taken out, and not only can influence the progress of operation, also can increase the risk of operation; And the cost of trepan is higher, if the trepan that often more renews increases the expenditure of hospital.
In addition, do not have scale on traditional trepan saw bar, the doctor can't judge accurately that trepan inserts the intravital length of people when undergoing surgery, and it is careful especially when using trepan, to need.
The utility model content
The purpose of this utility model is, a kind of novel trepan is provided, and it has sawtooth and is not easy fracture; The advantage of long service life; And can improve the toughness of sawtooth, and can recognize clearly that operation Shi doctor trepan inserts the intravital length of people, effectively reduce the risk of operation.
The technical scheme of this utility model: a kind of novel trepan, comprise saw bar, sawtooth and handle, sawtooth is located at an end of saw bar, and the other end of saw bar is provided with union joint, and handle is provided with the link slot that matches with union joint; The junction of any adjacent two teeth is a circular arc on the sawtooth.The junction of tooth and tooth is designed to the toughness that arc can increase tooth on the one hand, can effectively prevents the fracture of tooth on the other hand, also can not come off, effectively protect patient's safety, improve the success rate of operation from the saw bar even tooth and hair is given birth to bending.
In the aforesaid this novel trepan, the outer wall of saw bar is provided with scale, and scale is marked with corresponding scale value.Scale is set on the saw bar can lets the doctor recognize that clearly trepan inserts the intravital length of people, be convenient to better control the cutting quantity of trepan, improve the success rate of operation.
In the aforesaid this novel trepan, the top of sawtooth is " 0 " scale.
In the aforesaid this novel trepan, the cross sectional shape of the link slot on the handle is a pentagon.Adopt the pentagon design can make saw bar and handle bonded more firm, prevent to saw bar and in use shake.
In the aforesaid this novel trepan, be equipped with service aisle on saw bar and the handle.
In the aforesaid this novel trepan, the tooth on the sawtooth all tilts to clockwise direction.
In the aforesaid this novel trepan, the tooth on the sawtooth is all to counterclockwise tilting.Adopt the sawtooth of this inclination can make trepan cutting when single direction rotates in use; Then do not cut when rotating round about; When trepan takes out human body, can prevent effectively that trepan from hurting intravital other organs of people and tissue, improve the safety of operation.
Compared with prior art; Because this utility model is designed to arc with the junction of tooth and tooth; Effectively improved the toughness of sawtooth; Even and trepan sawtooth behind life-time service deforms also and can not come off from the saw bar, effectively reduce the risk of operation, solved the problem of traditional trepan sawtooth easy fracture;
Owing on the saw bar, increased scale, the doctor can see at any time that when using trepan trepan inserts the intravital length of people, the operation of being convenient to perform the operation, the risk of reduction operation.
Because the link slot on union joint and the handle is designed to pentagon, can improve the fastness that is connected between saw bar and the handle like this, solve traditional trepan behind life-time service, saw the problem of bar easy shaking.
