Detailed Description
Example 1: the quantitative opening device for clinical operation wounds shown in fig. 1 comprises an elastic steel ring 1 which can be automatically expanded in an unconstrained natural state. The head and the tail of the elastic steel ring 1 are partially overlapped.
The manual adjusting mechanism 3 is applied to the elastic steel ring 1, the elastic steel ring 1 which can be automatically unfolded under natural conditions is used as a supporting main body, the contractility of the elastic steel ring 1 is controlled by means of the control mode of the internal gear 38 and the rack 39, and therefore the contraction and expansion states of a plurality of supporting rods positioned at the lower side edge of the elastic steel ring 1 are controllable.
The specific structure of the manual adjusting mechanism 3 is shown in fig. 2, an end sleeve 2 is fixed at the head end of the elastic steel ring 1, and the overlapped part of the elastic steel ring 1 passes through the end sleeve 2. An internal gear 38 is mounted on the upper side in the end sleeve 2 through a rotating shaft 33, and a rack 39 is arranged on the upper side of the elastic steel ring 1 at the inner end part of the end sleeve 2, and the rack 39 is meshed with the internal gear 38.
The rotating shaft 33 of the inner gear 38 is sleeved with the hand wheel 31 after extending to the outer side of the end sleeve 2, the hand wheel 31 is connected with the rotating shaft 33 through a spline, as shown in the figure, the spline sleeve 32 is arranged on the outer side of the rotating shaft 33 in the axial direction of the hand wheel 31, and after the spline is matched with the spline sleeve, the rotating shaft 33 and the hand wheel 31 can be kept to rotate together, but the rotating shaft and the hand wheel can axially translate.
A baffle plate is provided at the end of the rotating shaft 33, and a thrust spring 35 is connected between the baffle plate and the hand wheel 31.
Meanwhile, a positioning tooth 36 parallel to the axial direction is arranged at the eccentric position of the inner side of the hand wheel 31, a clamping groove 37 is arranged on the side surface of the end sleeve 2 corresponding to the positioning tooth 36, and the positioning tooth 36 can be inserted into the clamping groove 37 to lock the hand wheel 31.
A plurality of vertical support rods are distributed on the lower side edge of the elastic steel ring 1 at intervals. The multi-angle support is carried out on the incisions by the plurality of support rods fully and uniformly, so that the effect of uniformly and dispersedly supporting is achieved, and the incision which is approximately circular is supported, so that the operation is more facilitated. The structure is very simple, but the operation is very convenient, and the use effect is good.
Example 2: on the basis of the embodiment 1, the support rod comprises a fixed support rod 4 fixed at the lower side edge of the elastic steel ring 1 and a movable support rod 5 sleeved at the lower side edge of the elastic steel ring 1. The upper end of the movable supporting rod 5 is fixed with a sliding sleeve 6, and the sliding sleeve 6 is sleeved with the elastic steel ring 1. A locking wire is arranged on the sliding sleeve 6.
Example 3: on the basis of the embodiment 1, an elastic piece 8 is sleeved outside the end sleeve 2. The device can realize slow adjustment through the manual adjustment mechanism 3, and can realize rapid automatic expansion through pressing the elastic plate. The inner ends of the positioning teeth 36 have wedge-shaped tips.
Referring to fig. 3 and 4, a symmetrical inclined elastic plate 9 is arranged at the lower side of the elastic member 8, a flat chute and an inclined chute 12 are arranged on the outer surface of the end sleeve 2, the upper side of the elastic member 8 is sleeved in the flat chute, and the inclined elastic plate 9 of the elastic member 8 is sleeved in the inclined chute 12. Thus, when the elastic member 8 is pressed, the inclined elastic plates 9 on both sides are contracted inward, and when the hand is released, the elastic member 8 can automatically pop up.
The lower side of the elastic piece 8 is provided with a sealing edge which is in butt joint with the upper edge of the clamping groove 37, and the clamping groove 37 can be sealed after the elastic piece 8 moves downwards.
The positioning teeth 36 can be shielded by the elastic member 8 in this embodiment, so that the positioning teeth 36 lose the locking function. At this time, the elastic steel ring 1 can be rapidly expanded. With this mode, a handle may be fixed at the tail end or the middle of the elastic steel ring 1 so as to be rapidly operated without using the manual adjusting mechanism 3.
