Abstract
A pulmonary blood vessel free forceps belongs to an auxiliary apparatus for lung operations, which comprises a left forceps body (1) and a right forceps body (2) which are hinged with each other and each are divided into a clamping jaw part (3) and a handle part (4) by the hinge joint. The front end of the clamping jaw part (3) is raised upward. The utility model is characterized in that the length L of the upward-raised portion of the clamping jaw part (3) is more than 1 cm, and the included angle (a) between the extension lines of the raised portion and the handle part (4) is larger than 90 degrees and smaller than 120 degrees. The utility model solves the problems in the prior art, such as small size of the front raised portion and unreasonable design of angle, and has the advantages that the forceps complies with the ergonomic principles, is easy to use, save labor, helps to increase the operation efficiency, reduce the operation time and improve the operation field.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of operating forceps, specifically a kind of lung blood vessel free forceps.
Background technology
At present, in pulmonary surgery, for the ease of operation, the lung blood vessel need be separated with lung tissue, wherein the most frequently used is the lung blood vessel free forceps, but for a long time, this lung blood vessel free forceps is because its forward perk size is little and the perk part rises almost in vertical state with pincers, operative doctor is very inconvenient in using, the one, because size is little, thicker blood vessel hook from lung tissue can't be gone out, and vertical binding clip is also very inconvenient when inserting lung tissue, be unfavorable for during operation observing and perform the operation convenient, in the time of therefore must be changed.
Summary of the invention
The purpose of this utility model is little, the irrational problem of angle of size that exists at existing lung blood vessel free forceps, designs a kind of use, operates all lung blood vessel free forceps very easily.
The technical solution of the utility model is:
A kind of lung blood vessel free forceps, comprise left caliper 1 and right caliper body 2, left caliper 1 and right caliper body 2 are hinged and connected, this pin joint is divided into binding clip part 3 and 4 two parts of pincers shank portion with left caliper 1 and right caliper body 2, the front end of described binding clip part 3 is upturned, the length L partly that is upturned that it is characterized in that described binding clip part 3 is greater than 1 centimetre, and this perk part is spent greater than 90 with the angle α that clamps shank portion 4 extended lines, less than 120 degree.
The length L of the part that is upturned of described binding clip part 3 is greater than 1.5 centimetres.
The part that is upturned of described binding clip part 3 is spent greater than 95 with the angle α that clamps shank portion 4 extended lines, less than 100 degree.
The utlity model has following advantage:
Free pincers of the present utility model are because the length of the perk part that extended, adjusted its angle of inclination, make it more to meet the principle of doctor's operating habit and ergonomics, make operative doctor choose when seeking the lung blood vessel more conveniently, and the art open country during operation is more satisfactory.By the clinical use surface of thousand examples only, it is the novel operation assistive device that a extremely meets principle of human engineering.
Description of drawings
Fig. 1 is the plan structure sketch map of free pincers of the present utility model.
Fig. 2 is the structural representation of facing of free pincers of the present utility model.
The specific embodiment
Following structure drawings and Examples are further described this utility model.
As shown in Figure 1, 2.
A kind of lung blood vessel free forceps, utilize the titanium alloy manufacturing, it comprises left caliper 1 and right caliper body 2, left caliper 1 and right caliper body 2 are hinged and connected, as shown in Figure 1, this pin joint is divided into binding clip part 3 and 4 two parts of pincers shank portion with left caliper 1 and right caliper body 2, wherein the binding clip part 3 of left caliper 1 is symmetrical with the binding clip part 3 of right caliper body 2, the symmetry of the pincers shank portion 4 of left caliper 1 and right caliper body 2 pincers shank portions 4, the front end of binding clip part 3 is upturned, and length L of its part that is upturned is greater than 1 centimetre, be preferably about 1.5 centimetres, this perk part is spent greater than 90 with the angle α that clamps shank portion 4 extended lines, and less than 120 degree, its optimum range is between the 95-100 degree.
This utility model does not relate to part, is provided with on the little toothing that strengthens contact force, pincers shank portion 4 in order to the buckle type governor motion of regulating closing force etc. all same as the prior art as the contact surface of two contacted binding clip parts 3 of closure of left caliper 1 and right caliper body 2.
Claims (3)
