Abstract
The invention relates to a medical surgical clamp matched with an endoscope, in particular to a visible surgical clamp with an endoscope sheath used for taking the intrauterine device out from the uterus. The existing visible surgical clamp is used in the birth control surgery, for example in the surgery to take the intrauterine device out from the uterus with the endoscope. Due to the easy bleeding of the endometrium tissue, the lens of the endoscope is easily contaminated to dim the surgery view, and the device is inserted in and taken out repeatedly for flashing, therefore the surgery time is prolonged and the operation is complicated. After the improvement, the groove formed after the side by side arrangement of the endoscope sheath and the drive rod is also fixed with two flush pipes (15) and (17), wherein the open of one flush pipe faces the open of the endoscope sheath (10), and the open of the other flush pipe faces a clamp head (6). A surgical cannula (5) is provided, and the water nozzle on the surgical cannula is communicated with a negative pressure source to absorb and remove the water of flushing. The improved surgical clamp provides clear surgery view, has compact integral structure and convenient operation, and can shorten the surgery time.
Description
(1) technical field
The present invention relates to a kind of and the matching used medical operating pincers of endoscope, especially for the visual operation pincers that have endoscope's sheath that take out intrauterine device from intrauterine.
(2) background technology
The basic structure of the matching used medical operating pincers of existing and endoscope comprises pincers seat, binding clip, drive link, drive link sleeve pipe, adjustable clamp handle; The drive link sleeve pipe is fixed on the pincers seat; The telescopic end of drive link is fixed with the fixed part of binding clip; Drive link is in the drive link sleeve pipe, and the adjustable clamp handle drives drive link, and drive link drives the movable part of binding clip.The structure of binding clip movable part has two types, and one type is linkage, and what the jaw list was opened is two linkages; Jaw is two, and what open is parallel four-bar linkage, the node of drive link articulated linkage mechanism back, and another kind of is the spring jaw; Jaw is dehisced under self resilient force, and the sleeve that when drive link pulling spring jaw moves backward, is fixed on drive link cover end forces jaw closed, and the structure that the adjustable clamp handle drives drive link has multiple; 1. connecting rod slider mechanism, 2. pincerlike jaw has shift fork, and shift fork is stirred the slide block that is fixed together with drive link; 3. spring handle, the free end of U-shaped spring is connected on the drive link, and so-called visual operation pincers are outside the drive link sleeve pipe of general operating forceps, to be fixed with endoscope's sheath side by side; The opening part of sheath is near binding clip, and endoscope's sheath is fixed on the pincers seat and goes up and pass usually the pincers seat, and the end of endoscope's sheath has the bayonet mount that connects endoscope; Above-mentioned these structures constituted multiple operating forceps; Specification has from 1 millimeter to 6 millimeters, and these structures all have displaying on the catalog of each big medical apparatus and instruments manufacturer, and CN200720021203.4 and CN200820016249.1 patent also have detailed description to this.The existing visual operating forceps is applied in the family planning operation; For example take out the operation of intrauterine device from intrauterine under the endoscope,, and situation such as incarceration of IUD is arranged because endometrial tissue is very easily hemorrhage; Be easy to cause endoscope lens to pollute; Make surgical field of view unclear, need insertion repeatedly to withdraw from apparatus and wash processing, therefore prolonged operating time and trivial operations.
(3) summary of the invention
The objective of the invention is: provide a kind of surgical field of view clear, compact overall structure, easy to operate visual operation pincers.
For reaching the object of the invention; Adopted following technical scheme: the visual operation pincers comprise pincers seat, binding clip, endoscope's sheath, drive link, drive link sleeve pipe, adjustable clamp handle, and endoscope's sheath and drive link sleeve pipe are fixed on the pincers seat, and the telescopic end of drive link is fixed with the fixed part of binding clip; Drive link is in the drive link sleeve pipe; The adjustable clamp handle drives drive link, and drive link drives the movable part of binding clip, is with the difference of prior art: also be fixed with two jet water spouts on the visual operation pincers; Wherein the opening of a jet water spout is towards the opening of endoscope's sheath, and the opening of another root jet water spout is towards binding clip.
For washing continuously; Be provided with the outside that a working column is enclosed within endoscope's sheath, drive link sleeve pipe, jet water spout; There is cutting ferrule the back of working column, and cutting ferrule cooperates with the deck of pincers seat raising, and water nozzle is arranged on the cutting ferrule; Water nozzle is communicated with the inner chamber of working column, and the interface of water nozzle is connected to vacuum extractor.
The pincers seat is a column; Endoscope's sheath and drive link sleeve pipe be fixed on side by side up and down that pincers seats is gone up and with the parallel axes of the pincers seat of column; Be fixed with jet water spout respectively in two grooves about endoscope's sheath and the formation of drive link sleeve pipe; The one side of pincers seat is raised with the deck that cooperates with working column, and the water nozzle of two jet water spouts is fixed on the pincers seat.
Be fixed with cover cap on the pincers seats, the other end of cover cap with cooperate with the endoscope deck, groove is arranged at the bottom of cover cap.
The locking claw that cooperatively interacts is arranged at the bottom of fixation clamps handle and adjustable clamp handle.
The visual operation pincers have two jet water spouts and bring several big benefits; One is that the water yield of two jet water spouts is bigger; The 2nd, can connect the negative pressure source suction by another root of jet water spout bath; Of paramount importance benefit is the camera lens of the opening of a wherein jet water spout towards the opening flushing endoscope of endoscope's sheath, and the opening of another root jet water spout washes operative region towards binding clip.
Therefore camera lens and operative region that visual operation pincers of the present invention can wash endoscope simultaneously easily have surgical field of view clearly; The interface of the water nozzle of working column is connected to vacuum extractor; Can wash continuously, the water nozzle that has the jet water spout of switch is fixed on the pincers seat, is fixed with cover cap on the pincers seat; The other end of cover cap with cooperate with the endoscope deck; The locking claw that cooperatively interacts is arranged at the bottom of fixation clamps handle and adjustable clamp handle, and these technological employings make that visual operation wrench structure compactness of the present invention is easy to use, can shorten operating time.
