Description

Microsyringe for department of stomatology

Technical Field

The utility model relates to a department of stomatology medical equipment technical field specifically is a microsyringe for department of stomatology.

Background

In the department of stomatology, need to carry out local anesthesia to the oral cavity, but because the position of oral cavity is too near to the brain, consequently need to control the quantity of anesthetic strict when carrying out the anesthesia, the quantity of anesthetic can damage the brain if too much, influence the anesthesia effect if too little, increase patient's misery, but at present in the department of stomatology anesthesia, all use ordinary syringe to carry out the injection of anesthetic, it is difficult to control to the quantity of anesthetic, very easily influence the operation, for this reason, we propose a department of stomatology use micro-injector.

Disclosure of Invention

An object of the utility model is to provide a microsyringe for department of stomatology to solve the problem that provides among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a microinjector for stomatology department comprises a tube body, wherein a threaded ring groove is formed in the upper end of the tube body, a threaded cylinder is screwed in the threaded ring groove, scale marks are arranged on the side surface of the threaded cylinder, a push handle is arranged at the upper end of the threaded cylinder, a through hole is formed in the push handle, one end of a push rod is arranged at the lower end of the push handle of the through hole, the other end of the push rod is arranged in a blind hole, the blind hole is formed in the upper end of a piston, the piston is arranged in the tube body, a seal sleeve is sleeved at the lower end of the piston, an injection head is arranged at;

a first anti-slip sleeve is sleeved outside the pipe body;

the second anti-skid sleeve is sleeved outside the push handle;

the number of the scale marks is four.

The utility model discloses a theory of operation and process:

when the microinjector is used, a needle head at one end of an injection head is pricked into an oral cavity, a push handle is rotated, a threaded cylinder on the push handle rotates and descends in a threaded ring groove, so that a push rod at the lower end of the push handle descends in a micro-scale mode, a piston is driven to descend in a micro-scale mode, anesthetic is injected into the oral cavity through the injection head, the amount of the injected anesthetic is observed through scale marks, and the amount of the injected anesthetic can be strictly controlled.

The utility model has the advantages that:

the utility model provides a microinjector for department of stomatology, it has the screw thread annular to open through the body upper end, it has the screw thread drum to connect in the screw thread annular, make the screw thread drum can go up and down in screw thread annular internal rotation, install the scale mark through screw thread drum side, make the lift volume of screw thread drum can be convenient for observe, install the push handle through screw thread drum upper end, it has the through-hole to open on the push handle, make rotatory push handle can drive the screw thread drum rotatory lift, push rod one end is installed through-hole push handle lower extreme, the push rod other end is installed in the blind hole, the blind hole is seted up in the piston upper end, make the push rod can go up and down along with the screw thread drum rotation, the piston can be the micro-lift from.

Detailed Description

Referring to fig. 1 and 2, a microinjector for stomatology comprises a tube body 1, wherein a threaded ring groove 101 is formed at the upper end of the tube body 1, a threaded cylinder 2 is screwed in the threaded ring groove 101, so that the threaded cylinder 2 can rotate and lift in the threaded ring groove 101, a scale mark 11 is installed on the side surface of the threaded cylinder 2, so that the lift amount of the threaded cylinder 2 can be conveniently observed, a push handle 3 is installed at the upper end of the threaded cylinder 2, a through hole 301 is formed in the push handle 3, so that the threaded cylinder 2 can be driven to rotate and lift by the rotation of the push handle 3, one end of a push rod 4 is installed at the lower end of the push handle 3, the other end of the push rod 4 is installed in a blind hole 501, the blind hole 501 is formed at the upper end of a piston 5, so that the push rod 4 can rotate and lift along with the threaded cylinder 2, the piston 5 can slightly lift up and down, an injection head 8 is mounted at the lower end of the tube body 1, and a fixing sleeve 7 is sleeved outside the injection head 8, so that the injection head 8 is firmly fixed;

the first anti-slip sleeve 9 is sleeved outside the pipe body 1, so that the pipe body 1 is convenient to hold by hands;

the second anti-skid sleeve 10 is sleeved outside the push handle 3, so that the push handle 3 is convenient to hold and rotate;

the number of the scale marks 11 is four, so that the lifting amount of the threaded cylinder 2 is convenient to observe.

The utility model discloses a theory of operation and process:

referring to fig. 1 and 2, in the micro-injector for stomatology, when in use, a needle at one end of an injection head 8 is pricked into an oral cavity, a push handle 3 is rotated to rotate and descend a threaded cylinder 2 on the push handle 3 in a threaded ring groove 101, so that a push rod 4 at the lower end of the push handle 3 is slightly descended, a piston 5 is driven to slightly descend, anesthetic is injected into the oral cavity through the injection head 8, and the amount of the injected anesthetic is observed through a scale line 11, so that the amount of the injected anesthetic can be strictly controlled.
