Description

Nasal septum extraction knife

Technical Field

The utility model belongs to the technical field of surgical operation instrument, specifically be a nasal septum draws sword.

Background

The comprehensive plastic operation of nose is the nasal plastic operation that is comparatively prevalent at present, at the in-process of drawing the septum cartilage of nose, because the field of vision is narrow and small, the below and the rear of septum cartilage of nose can't show clearly, the doctor can only use scalpel or cartilage incision sword, rely on personal experience and sense to surely get, can not guarantee fully to surely get monoblock septum cartilage of nose, septum cartilage is both thin and fragile simultaneously, the dynamics is mastered inaccurately, cut through contralateral pia mater or mucosa easily, lead to bleeding endlessly, and be compelled to stop septum cartilage and surely get the operation. The prior art also has a nasal septum extracting knife specially used for extracting the nasal septum, which is mainly composed of a knife head 1, a knife head worm 2 and a knife bar 3 as shown in figure 1. The cutter head is straight, and in the process of extracting the nasal septum, because the congenital characteristics of the autologous cartilage of the nasal septum can often cause incomplete material taking, crushing and waste of autologous material resources, prolong the operation time, improve the operation infection probability and the like. In view of the above, there is a need for improved and more recent techniques for conventional nasal septum extraction knives that better facilitate the performance of the procedure while reducing trauma to the patient.

SUMMERY OF THE UTILITY MODEL

The utility model provides an among the prior art foretell problem, the utility model provides a nasal septum draws sword, the purpose of realization does, according to nasal part physiological structure, improves the nasal septum among the prior art and draws the sword, reduces the surgical instruments of patient's damage, and the scalpel after the improvement is more convenient in medical treatment operation process, saves time, and is safer, very big improvement the operation effect, has reduced infection complication etc. that leads to because of the time overlength in the art.

In order to achieve the purpose, the utility model provides a technical scheme does, the utility model provides a pair of nasal septum draws sword, including the tool bit, with tool bit integrated into one piece's tool bit worm to and the cutter arbor that links together with the tool bit worm, the tool bit is radian bending shape, and the angle of the radian that bends is 45, and the position department of adjacent tool bit worm installs the miniature lamp on the cutter arbor.

The utility model discloses through a large amount of clinical simulation experiments, design out the tool bit that accords with nasal part physiological structure, can play the quick, the complete of drawing materials, reduce the effect of bleeding, the miniature lamp of addding helps the doctor to see the inside structure of nose.

Further, the cutter bar is in threaded connection with the cutter head worm. By adopting the simple detachable connection mode, the cutter head worm can be conveniently replaced so as to be suitable for different operations.

Furthermore, the cutter bar comprises a first hollow tube and a second hollow tube, the second hollow tube is wrapped and sleeved on the first hollow tube, positioning holes A and B which penetrate through the first hollow tube and the second hollow tube are formed in the first hollow tube and the second hollow tube, positioning pins are inserted into the positioning holes, elastic blocking pieces are fixed on the inner wall of the first hollow tube, and the end portions, penetrating into the first hollow tube, of the positioning pins are connected with the elastic blocking pieces. The cutter bar is designed to be telescopic, so that the cutter bar is different from person to person, and an operator can feel more comfortable.

Furthermore, an anti-skid layer is adhered to the knife handle. The added anti-slip layer effectively prevents hands from falling off, and avoids operation risks.

The utility model adopts the above technical scheme, beneficial effect includes: the utility model discloses a this kind draws sword has the tool bit that accords with nasal part physiological structure, can play draw materials rapidly, draw materials completely, reduces the effect of bleeding to protection autologous material is not wasted, and the at utmost alleviates the damage of disease, has shortened operation time, has improved the security.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The first embodiment is as follows: the utility model provides a pair of nasal septum draws sword, refer to figure 2 and show, including tool bit 1, with tool bit integrated into one piece's tool bit worm 2 to and the cutter arbor 3 that links together with the tool bit worm, the tool bit is the radian bending shape, and the angle of crooked radian is 45, and the position department of the last adjacent tool bit worm of cutter arbor installs miniature lamp 4. The used miniature lamp can adopt a miniature lamp bead, an LED lamp bead and the like in the prior art.

Example two: in addition to the structure disclosed in the first embodiment, in order to further optimize the present invention, as shown in fig. 3, the cutter bar is connected with the cutter head worm by a thread 5 (in order to be able to see the thread structure of the internal screw joint clearly, the figure actually adopts a profile processing).

Further, referring to fig. 4 (in order to clearly see the internal structure, this figure actually adopts partial section processing), the cutter bar includes a first hollow tube 6 and a second hollow tube 7, the second hollow tube is wrapped and sleeved on the first hollow tube, positioning holes A8 and B9 which penetrate through each other are formed on the first hollow tube and the second hollow tube, a positioning pin 10 is inserted into the positioning holes, an elastic blocking piece 11 is fixed on the inner wall of the first hollow tube, and the end of the positioning pin penetrating into the first hollow tube is connected with the elastic blocking piece. The elastic blocking piece can be made of any material with elastic deformation in the prior art, such as a spring. When pressing down the locating pin, the locating pin removes to first hollow tube direction, and the second hollow tube then can move about this moment, will remove the second hollow tube when suitable locating hole, unclamp the locating pin again, the locating pin gets back to under the effect of elastic retaining piece like this in the locating hole with the locating hole card on the second hollow tube realize fixing in the locating hole to this adjusts the length of cutter arbor, thereby is applicable to different operators.

Further, an anti-skid layer 12 is attached to the knife handle.

The above description is only a preferred embodiment of the present invention, and the present invention is not limited thereto, but can be modified and changed by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
