Description
Technical field
The utility model belongs to medical instruments field, is specifically related to a kind of abdominal puncture needle.
Background technique
Abdominal puncture needle is to control in laparoscopic minimally invasive surgery for extracting in-vivo tissue or excluding hydroabdomen or inject
Treat the common instrument of drug.Currently, puncture needle, during knit stitch, the depth of knit stitch is mainly manually controlled by operating doctor,
This just has high requirement to the skill proficiency of doctor, and knit stitch shallowly then be easy to cause puncture insufficient excessively, and knit stitch is too deep and holds
Organ in easy damaged patient's abdomen.Meanwhile existing abdominal puncture needle is easy to appear certain deflection during knit stitch, from
And huge pain is increased to patient.
Summary of the invention
The purpose of this utility model is to provide a kind of abdominal puncture needles that can improve knit stitch accuracy.
For achieving the above object, the technical scheme adopted by the utility model is a kind of abdominal puncture needle, including needle
Seat and the needle body that needle stand bottom is set；It further include guide holder, the guide holder is by guide pipe and guiding bottom of the tube is arranged in
Silica gel disk is constituted, and is vertically provided with the through-hole matched with needle body in the guide holder, the guide holder is arranged by through-hole
On needle body；Connecting plate is arranged in the surface of the guide pipe side, and the upper surface setting of the connecting plate is parallel with needle body to be led
To bar, graduation mark is provided on the guide rod；The needle stand side opposite with connecting plate is provided with to be matched with guide rod
Guide sleeve, the upper end of the guide rod is threaded through in guide sleeve；The side of the guide sleeve is provided in perforation to guide sleeve
Threaded hole, and locking bolt is fitted in threaded hole.
Preferably, drainage tube and gas tube are additionally provided on the needle stand, the spherical valve chamber of setting, described to draw inside needle stand
Flow tube, gas tube and needle body are connected to valve chamber；Spool is additionally provided in the valve chamber, the spool is by being located at needle stand side
Switch handle control.
Preferably, the bottom surface of the silica gel disk is disposed with adhesive layer and adhesive layer protective film from the inside to the outside.
The beneficial effects of the utility model embody a concentrated reflection of, and can effectively mark out the depth of puncture needle knit stitch, and
Needle body can be effectively oriented to during knit stitch, stability is high, easy to use.Specifically, the utility model
In use, silica gel disk is attached in patient abdomen, the part scale value that guide rod is pierced by outside guide sleeve at this time is zero.So
Afterwards, locking bolt is unclamped, buttresses guide pipe on the other hand, another hand presses pressure needle seat, needle body is slowly promoted into patient's abdomen.It is pushing away
During, pay attention to observing the graduation mark on guide rod, when the part graduation mark that guide rod is pierced by guide sleeve reaches designated value
Afterwards, silica gel disk is fixed on patient abdomen with medical proof fabric.Then locking bolt is tightened again.The utility model, due to setting
The graduation mark set on the guide bar can effectively indicate knit stitch depth, and guide holder can effectively be oriented to needle body,
Therefore, it can be improved the stability during knit stitch, reduce the operation difficulty of doctor.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is a kind of use state diagram of structure shown in Fig. 1；
Fig. 3 is the schematic diagram of internal structure of needle stand；
Fig. 4 is a kind of use state diagram of structure shown in Fig. 3.
Specific embodiment
A kind of abdominal puncture needle in conjunction with shown in Fig. 1-4, including needle stand 1 and the needle body 2 that 1 bottom of needle stand is arranged in.Also wrap
Guide holder is included, for the guide holder for being oriented to during knit stitch to needle body 2, the guide holder is by guide pipe 3 and sets
The composition of silica gel disk 4 in 3 bottom of guide pipe is set, is vertically provided with the through-hole matched with needle body 2 in the guide holder, it is described
Guide holder is set on needle body 2 by through-hole.The surface of 3 side of guide pipe is arranged connecting plate 5, the connecting plate 5 it is upper
The guide rod 6 parallel with needle body 2 is arranged in surface, is provided with graduation mark on the guide rod 6, the guide rod 6 is usually by resin
It is made.The needle stand 1 side opposite with connecting plate 5 is provided with the guide sleeve 7 matched with guide rod 6, the guide rod 6
Upper end is threaded through in guide sleeve 7.The side of the guide sleeve 7, which is provided with, to be penetrated through to the threaded hole in guide sleeve 7, and in threaded hole
Inside it is fitted with locking bolt 8.
The utility model in use, silica gel disk 4 is attached in patient abdomen, guide rod 6 is pierced by guide sleeve 7 at this time
Outer part scale value is zero.Then, locking bolt 8 is unclamped, buttresses guide pipe 3 on the other hand, another hand presses pressure needle seat 1, by needle
Body 2 is slowly promoted into patient's abdomen.During propulsion, pay attention to observing the graduation mark on guide rod 6, when guide rod 6 is pierced by
After the part graduation mark of guide sleeve 7 reaches designated value, silica gel disk 4 is fixed on patient abdomen, better way with medical proof fabric
