The shaft of the component can maintain the state of the control mechanism regardless of the upper and lower dead points, and the effect is simple and practical. [Embodiment] The present invention is a lockable medical surgical instrument. As shown in the first figure, a substantially gun-shaped body (1) has an elongated outer tube (16) at one end, and the outer tube (16) The end system is connected to a clamping mechanism (2〇), and the body (1〇〇) has first and second handles (101) (30). 8 200822900 Please refer to the second and third figures, the body (100) comprises a grab-shaped base body (10) and a casing (13) for covering the base body (10), wherein the base body (10) and the shell The body (13) is formed on the opposite side to form a ring-shaped grip (11) (14) for the fingers to extend, whereby the two grips (11) (14) are correspondingly engaged to form the first handle body (1) 01), the base body (1 〇) protrudes from the side of the adjacent handle (11) with a column portion (12), and an outer tube (16) is fixed to the base body (1〇), and the other end is straight outward. Extend out. The clamping mechanism (20) is as shown in the first, second, and fourth figures. The clamping mechanism (20) includes an inner rod (21) and two short rods (23) mounted inside the outer tube (16). Two clamp arms (24). The end of the inner rod (21) extending from the outer tube (16) is pivotally connected to one end of the two short rods (23), and the other ends of the two short rods (23) are respectively pivotally connected to one end of each of the clamping arms (24), two The clamping arms (24) are pivotally disposed at one end of the end tube (22) at the intersection of each other, and the other end of the end tube (22) is fixedly welded to the end of the outer tube (16), thereby being connected by the inner rod (21). Two short rods (23), and the two clamp arms (24) are pivotally connected to the outer tube (16) by the end tube (22), so that the inner rod (21) is displaced, that is, the two short rods (23) are interlocked, so that It drives the two clamp arms (24) to open or close with their pivotal connection to the end tube (22). As shown in the second and third figures, a second handle body (3〇) has an annular body for the fingers to be stretched and held, and the other side forms two arms to be placed at one of the arms. Side (31), the other arm is a stop side (32), wherein the touch side (31) is freely rotatable on the base body (1) and is placed on the top side and inside the outer tube (16) The rod (21) is connected to the end to grip the first and second handles (11) (30), thereby pulling the inner rod (21) to be displaced in the outer tube (16), so that the clamping mechanism (20) The two clamp arms (24) are actuated, and the inner side of the stop side (32) on the side of the 200822900 forms a ratcheting tooth (321). a limiting body (40) is attached to the inner surface of the base body (10) and is close to the stopping side (32), and the limiting body (4〇) is formed by a convex strip, such as a closed soil. The shape of the inner protrusion is the up part (41), and the two inner sides adjacent to the stop (41) are the lower and upper positions, which are the bottom dead center (42) and the top dead center (43), respectively. The inner side of the bottom dead center (43) (42) is an arc, and the restricted body (4 turns) is inclined so that the top dead center (43) is farther from the column portion (12) than the bottom dead center (42). The locking member (50) has an arc-shaped pressing portion and an arm portion (52) extending from the pressing portion (51). The arm portion (52) has a long hole corresponding to the column portion (12). (521), the locking element (5〇) is movably movable with the column portion (12) as a fulcrum, and the end portion of the arm portion (52) is provided with a circular block shaft portion (53) for the limiting body ( 40) The inner movable displacement, and the pressing portion (51) is as shown in the first figure, the exposed body (100) is used for the hand to be pressed or relaxed. A guiding block (60) is elastically pivoted on the In the base body (1〇), it is a curved squash-like block, and the 'face is a ratchet-like limit. (61) for engaging with the latch (321), and the other end is a pivot portion (62) rotatably provided on the base body (1), and the position of the opposite guide block (60) is attached to the base body (1) The upper pivoting member is a torsion spring-like elastic generating element (63). One end of the elastic element (63) abuts against the corresponding protruding rib on the base body (1〇), and the other end is abutted against the guiding block (6). 〇) opposite to the back side of the locking element (50) direction, and according to the maintenance of the locking element (5〇), the outer side of the shaft portion can contact the guiding block (60), providing a control to press the guiding block ((8) Displacement to achieve the purpose of engaging the second handle (3〇). The basic state of use is to hold the second handle (3〇), and the touch side (31) pushes the inner rod (21) forward, Even if the two short rods (23) are linked to each other, the two clamp arms (24) 200822900 are opened, and vice versa, the aforementioned clamping mechanism (2) is not a feature of the present invention, and is only briefly described herein. When the clamp arm (24) is opened or closed at any angle state, the limit restriction can be performed only by a single action of the lock-up element (5〇). As shown in the second and fifth figures, When the set opening angle of the two clamp arms (24) is maintained, the pressing portion (51) of the lock lock member (50) is pressed, and the long hole (521) is retracted along the column portion (12) to form the shaft portion (53) at the stop portion. (41) In the lower dead center (42) below, since the upper portion is blocked by the stopper (41), the shaft portion (53) is restricted thereto, and the elastic force of the elastic member (63) forces the push block (6〇). ) abutting against the shaft portion (53), so the limiting teeth (61) and the latching teeth (321) are barbed teeth, restricting the second handle body (30) from moving, locking and holding the two clamping arms (24) The opening angle at this time. Similarly, as shown in the second and sixth figures, if the second handle body (3〇) is to maintain the two clamp arms (24) in the closed state, the control lock member (50) is also pressed to make the shaft portion ( 53) touching the guide block (60), forcing the guide block (6〇) to engage and bite the second handle body (30), so that the second handle body (3〇) can no longer freely drive the second handle body (30); Regardless of whether the clamping mechanism (2〇) is opened or closed, the second handle body (3〇) can be controlled to remain locked by the control lock member (50) and the restricting body (40). Conversely, if you want to unlock the state, as shown in the second, fifth, and seventh diagrams, just pull back the lock component (50) and move the long hole (521) along the column (丨2) to overcome the elastic component (63). The elastic force causes the shaft portion (53) to rotate in a direction opposite to the stop portion (41), and pushes the shaft portion (53) of the guide block (60) to shift to the top dead center along the range of the limit body (40) 200822900. (43), so that the guide block (60) is rotated and retracted in the upper direction, so that the limiting teeth (61) are disengaged from the engaging teeth (321), and the elastic restoring force of the elastic member (63) is used to push the guiding block ( 6 0 ) still abuts the shaft (5 3 ), and because the shaft (5 3 ) is limited by the stop (41), it will not easily return to the bottom dead center (4 2 ), so that it can be pressed or pulled By controlling the single action of the lock element (50), it is possible to maintain the lock or unlock state, thereby eliminating the inconvenience of double operation. The above embodiments are merely illustrative of the technology and its effects of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify and change the above embodiments without departing from the technical spirit and spirit of the present invention.
