Abstract
The utility model provides a pair of blood vessel free forceps. The pair of blood vessel free forceps comprises a left annular handle, a left forceps arm, a left forceps head, a right annular handle, a right forceps arm, a right forceps head and an articulated shaft hinged to the two forceps arms and is characterized in that the left forceps head and the right forceps head are tilted upwards from the plane where the left forceps arm and the right forceps arm are located and are deflected towards the same side; and the maximum deflection angles of the left forceps head and the right forceps head towards the same side are 10-30 degrees. During minimally invasive pneumonectomy of chest, the forceps heads are conveniently inserted in lung tissue without influencing the observation of an operator at the same time, so that blood vessels of lung are freed accurately, and the operation is convenient and quick to complete. The pair of blood vessel free forceps is simple in structure and convenient to process and manufacture.
Description
Technical field
This utility model belongs to manufacture technology field of medical appliance, relates to a kind of medical apparatus that is mainly used in the operations such as chest Wicresoft pneumonectomy, is a kind of blood vessel free forceps specifically.
Background technology
Day by day universal along with chest Wicresoft pneumonectomy operation, to pulmonary vascular free and exposure, usually adopt the traditional operation apparatus: little right angle forceps or large curved hemostatic forceps, because jaw length and the opening length of these two kinds of pincers reaches jaw perk angle deficiency not, make the free of blood vessel and insert scope stapler difficulty, being not easy to observe, operate.
Chinese patent (the patent No.: ZL200720036161.1) disclose a kind of lung blood vessel free forceps, length and the angle of binding clip perk have been done to improvement, but the binding clip of perk has usually blocked operator's sight line, thoroughly do not solved yet unhandy problem.
Summary of the invention
The problems referred to above that this utility model exists for solving prior art, a kind of blood vessel free forceps is provided, associated jaw portion is further improved, when the pneumonectomy operation of chest Wicresoft, make binding clip be convenient to insert lung tissue, do not affect simultaneously the operator and observe, be convenient to accurately dissociate pulmonary vascular, complete quickly and easily operation.
The purpose of this utility model is achieved through the following technical solutions:
A kind of blood vessel free forceps, comprise: the jointed shaft of left annular hand grip, left clamp arm, left binding clip, right annular hand grip, right clamp arm, right binding clip and hinged two tong arms, it is characterized in that, described left binding clip and right binding clip are from left clamp arm and plane, right clamp arm place is upturned and to the same side deflection.
To improvement of the technical scheme: described left binding clip and right binding clip are 10 °-30 ° to the maximum angle of the same side deflection
To further improvement in the technical proposal: described left binding clip and right binding clip first sink and are upturned from left clamp arm and plane, right clamp arm place, and left binding clip and right binding clip form hook solid.
To further improvement in the technical proposal: the be upturned length of part of described left binding clip and right binding clip is 20-40mm.
To further improvement in the technical proposal: on the medial surface of described left binding clip and right binding clip, two binding clip contacts site arrange the anti-skidding groove of stinging.
To further improvement in the technical proposal: described left annular hand grip, left binding clip and left clamp arm are the integrative-structure that rustless steel or titanium are made, and described right annular hand grip, right binding clip and right clamp arm are the integrative-structure that rustless steel or titanium are made.
This utility model compared with prior art has the following advantages and good effect:
The left binding clip of this utility model blood vessel free forceps and right binding clip are from left clamp arm and plane, right clamp arm place is upturned and to the same side deflection.The angle that left binding clip and right binding clip are upturned is convenient to insert lung tissue, left binding clip and right binding clip can not block operator's sight line to the angle of the same side deflection, the groove of stinging of binding clip contact site has been avoided the blood vessel slippage that dissociates, be convenient to accurately dissociate pulmonary vascular, complete quickly and easily operation.It is simple in structure, and processing and fabricating is convenient.
The accompanying drawing explanation
Fig. 1 is the axonometric chart of this utility model blood vessel free forceps;
Fig. 2 is the left binding clip of this utility model blood vessel free forceps or the schematic diagram that right binding clip turns to a lateral deviation;
Fig. 3 is the left binding clip of this utility model blood vessel free forceps or the schematic diagram that right binding clip is upturned;
In figure: the right annular hand grip of 1-, 2-left clamp arm, 3-right clamp arm, 4-jointed shaft, the left binding clip of 5-, the right binding clip of 6-, the anti-skidding groove of stinging of 7-.
The specific embodiment
Referring to Fig. 1-Fig. 3, the embodiment of a kind of blood vessel free forceps of this utility model comprises: left and right annular hand grip 1, left clamp arm 2, right clamp arm 3, jointed shaft 4, left binding clip 5, right binding clip 6, left clamp arm 2 is hinged by jointed shaft 4 with right clamp arm 3.Left binding clip 5, right binding clip 6 are upturned and (left or right) deflection to the same side from left clamp arm 2 and right clamp arm 3 planes, place.Left binding clip 5 and right binding clip 6 are 10 °-30 ° to the maximum angle of the same side deflection
Preferred concrete structure is: as shown in Figure 3,6, left binding clip 5 and right pincers first sink and are upturned from left clamp arm 2 and right clamp arm 3 planes, place, when being upturned to the same side deflection, make left binding clip 5 and right binding clip 6 form round and smooth hook solid, the be upturned length of part of left binding clip 5 and right binding clip 6 is 20-40mm.
Two binding clip contacts site arrange the anti-skidding groove 7 of stinging on the medial surface of left binding clip 5 and right binding clip 6.Left annular hand grip, left binding clip 5 and left clamp arm 2 are the one knot that rustless steel or titanium are made
Structure, right annular hand grip 1, right binding clip 6 and right clamp arm 3 are the integrative-structure that rustless steel or titanium are made.
During use, coagulation hook or ultrasound knife cut between the mediastinal pleura of blood vessel surface or leaf after pleura and blood vessel sheath, with blood vessel free forceps of the present utility model, go deep into gradually gap, expansion rear, blood vessel rear, because its left binding clip 5 is difficult for the organizational structure at injured blood vessel rear and does not stop operator's sight line with the distinctive radian of right binding clip 6, when hemorrhage, can directly use with the anti-skidding left binding clip 5 of stinging groove 7 and need not change apparatus with right binding clip 6 clamping blood vessels.Both can be used for Minimally Invasive Surgery, also be convenient to traditional operation.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and this utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of having done, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
