Description
Technical field
The utility model is related to medical appliance field, specially a kind of not damaged sponge forceps.
Background technology
In endoscope-assistant surgery, sponge forceps is mainly used for carrying out the clamping of tissue or blood vessel, the behaviour such as moves to be cut, to be moved
Make, existing sponge forceps is divided into two types anodontia and with teeth, because of folder if selecting anodontia sponge forceps to carry out endoscope-assistant surgery
It holds and loosely easily slips, but be easy to blood vessel according to sponge forceps with teeth or organize to cause certain damage, increase trouble
The pain of person is unfavorable for the postoperative rehabilitation of patient.
Utility model content
The purpose of this utility model is to provide a kind of not damaged sponge forceps, can effectively solve the problems in background technology.
Realizing the technical solution of above-mentioned purpose is：A kind of not damaged sponge forceps, it is characterised in that：Including jaw and handle,
It is provided between the jaw and handle and stretches bar, handle includes left handle and right handles, and the jaw includes upper jaw under
Jaw, the lower jaw are fixedly connected on the one end for stretching bar, and the upper jaw, which is movably connected in, to be stretched on bar, described to stretch bar
For hollow tubular, described stretch is provided with traction steel wire in bar, one end of the traction steel wire is connect with handle, the traction steel
The other end of silk is connected with upper jaw, and the traction steel wire can drive upper jaw to make to open or be closed fortune relative to lower jaw
It is dynamic；
The upper jaw and lower jaw are in oval ring-type, and the upper jaw and lower jaw are respectively arranged with centre bore, upper pincers
The opposite flank of mouth and lower jaw is circumferentially provided with mutually matched annular protrusion and annular groove, and annular protrusion and annular are recessed
The section of slot is arc-shaped.
Further, the lower jaw has angle with bar is stretched.
Further, lower jaw and the corner dimension stretched between bar are 110~170 °.
Further, mutually matched first engaging section and the second engaging section are provided between left handle and right handles, the
One engaging section is meshed with second engaging section when jaw is mutually closed, and site of engagement is zigzag.
Further, the upper jaw and lower jaw opening angle are 25~60 °.
Further, the length of the sponge forceps is 250~500mm.
The beneficial effects of the utility model：The utility model has the advantages of simple structure, compact to design, easy to use, upper jaw and
The opposite flank of lower jaw is circumferentially provided with mutually matched annular protrusion and annular groove, makes sponge forceps in endoscope-assistant surgery
Clamping is more securely unlikely to slip when for tissue or blood vessel to be clamped, and the tissue of clamping can not be damaged in clamping process
Or blood vessel, improve operation level.
Mutually matched first engaging section and the second engaging section are provided between left handle and right handles, what jaw was meshed
In the process, the first engaging section and the intermeshing of the second engaging section, user need not continue firmly still to may make the jaw of sponge forceps
It mutually clamps, clamping effect is ideal.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of upper jaw and lower jaw clamped condition；
Fig. 3 is the structural schematic diagram of mutually matched first engaging section and the second engaging section.
Specific implementation mode
As shown in Figure 1, 2, 3, the utility model includes jaw 1 and handle 2, is connected between jaw 1 and handle 2 and stretches bar
3, handle 2 includes left handle 21 and right handles 22, and left handle 21 is fixedly connected with bar 3 is stretched, and right handles 22 are logical with left handle 21
Axis pin rotation connection is crossed, jaw 1 includes upper jaw 11 and lower jaw 12, and lower jaw 12 is fixedly connected on the one end for stretching bar 3, on
Jaw 11, which is movably connected in, to be stretched on bar 3, and it is hollow tubular to stretch bar 3, is stretched and is provided with traction steel wire in bar 3 and (does not show in figure
Go out), one end of the traction steel wire is connect with right handles 22, and the other end of traction steel wire is connected with upper jaw 11, draws steel
Silk can drive upper jaw 11 to make opening or closing motion relative to lower jaw 12.
Upper jaw 11 and lower jaw 12 are in oval ring-type, and upper jaw 11 and lower jaw 12 are respectively arranged with centre bore 4, upper pincers
The opposite flank of mouth 11 and lower jaw 12 is circumferentially provided with mutually matched annular protrusion 6 and annular groove 5, annular protrusion 6
It cooperates with annular groove 5, sponge forceps is made more securely to be unlikely to for clamping when tissue or blood vessel is clamped in endoscope-assistant surgery
It slips.And the section of annular protrusion 6 and annular groove 5 is arc-shaped, and the tissue of clamping can not be damaged in clamping process
Or blood vessel, improve operation level.
7 and second engaging section 8 of mutually matched first engaging section, jaw 1 are meshed between left handle 21 and right handles 22
During, the first engaging section 7 and the intermeshing of the second engaging section 8, site of engagement is zigzag.User need not persistently use
