Abstract
The utility model discloses a cardiac surgery forceps cannula fixer which relates to a cardiac minorapproach surgery appliance and comprises a forceps body, wherein the forceps body is mainly formed by two mutually hinged forceps arms, the front end of each forceps arm is provided with an arc structure, the two arc structures surround to form a circular tube, and the axle wire of the circular tube is not parallel to forceps arms bodies. When in cardiac minorapproach surgery, the two arc jaw structures at the front end of the cannula fixer clamp the cannula along the axes for the intubating operation during the surgery intubating, thereby the defect that the hand can not operate the surgery because of the weakness of the softness of the tube and the small space is avoided, the stability of the deep vision operation is increased, the surgery risk is lowered, and the surgery time is reduced.
Description
Technical field
This utility model relates to a kind of medical operation apparatus, specifically, relates to a kind of heart small incision surgery intubate holder.
Background technology
When adopting mini-invasive incision to carry out operation on heart, in setting up the extracorporeal circulation process, adopt tweezers or mosquito forceps clamping aortic cannulation or superior and inferior vena cava intubate mostly, perfect aspect outer circulation intubate in the past.In carrying out this operating process, because tweezers or mosquito forceps fixed-piping shakiness, and thereby surgical field of view is dark, otch is little is difficult for free-hand operation and has increased operating time and operation risk, therefore, be necessary for very much heart small incision surgery configuration intubate holder, with the minimizing operating time, and increase operation safety.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that the visual field is dark in the existing mini-invasive incision operation on heart process, otch causes the intubate operating difficulties for a short time, a kind of jaw type intubate holder to be provided, reducing operating time to reduce operation risk.
For achieving the above object, the technical solution adopted in the utility model is: a kind of operation on heart jaw type intubate holder, comprise caliper, described caliper mainly is made up of two tong arms that are hinged, the front end of each tong arm has arcuate structure, two arcuate structures hold and form a pipe, and the axis of described pipe and the body of tong arm are not parallel.
Preferably, described tong arm end is provided with handle.
Preferably, all be provided with the horizontal pawl of band ratchet on described two tong arms near handle part, the horizontal pawl yin-yang match of the band ratchet on two tong arms.
The beneficial effects of the utility model are: when operation, utilize two arc vice jaw structures of its intubate holder front end direct-axis heart to vise intubate, carry out the intubate operation.Avoided the soft weakness of body, increased the stability of dark visual field operation, reduced operation risk and reduced operating time.
Description of drawings
Fig. 1 is the structural representation of jaw type intubate holder of the present utility model;
Fig. 2 is the side view of the jaw type intubate holder of a kind of implementation column of this utility model;
Fig. 3 is the side view of the jaw type intubate holder of a kind of implementation column of this utility model;
Fig. 4 is the side view of the jaw type intubate holder of a kind of implementation column of this utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to Fig. 1, a kind of operation on heart jaw type intubate holder, comprise caliper, described caliper is mainly by two tong arms that are hinged 1,2 form, the front end of tong arm 1 has arcuate structure 11, the front end of tong arm 2 has arcuate structure 21, arcuate structure 11,21 form a pipe 3, the axis of described pipe 3 and the body of tong arm are not parallel, tong arm 1 end is provided with handle 12, and tong arm 2 ends are provided with handle 22, is provided with the horizontal pawl 13 of band ratchet on the tong arm 1 near handle 12 positions, be provided with the horizontal pawl 23 of band ratchet on the tong arm 2 near handle 22 positions, horizontal pawl 13,23 yin-yang match.
With reference to Fig. 2, side view for last cannula cavity holder, with reference to Fig. 3, side view for following cannula cavity holder, with reference to the side view of Fig. 4 aortic cannulation holder, as can be seen from the figure, last cannula cavity holder, following cannula cavity holder and aortic cannulation holder have structure much at one, unique difference is: because the difference of surgery location, its arcuate structure is different with the angle of tong arm body.
When operation, utilize two arc vice jaw structures of its intubate holder front end direct-axis heart to vise intubate, carry out the intubate operation.The stability of having avoided the soft weakness of body to increase the operation of the dark visual field has reduced operation risk and has reduced operating time.
Being this utility model preferred embodiment only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of this utility model claim change and modification, all should belong to technology category of the present utility model.
