Abstract

The invention relates to a lower and left protective curtain of a DSA (digital drainage bed) operating bed, which comprises a first arm, a second arm, a third arm, a pin shaft, a connecting sleeve, a sliding rail, a curtain pressing plate and a lead protective soft curtain. The second section arm is connected with the first section arm through a pin shaft and a connecting sleeve; the upper end part of the connecting sleeve is inserted into the central hole of the first knuckle arm; the sliding rail is arranged on the second section arm; the third section arm is arranged on the sliding rail, and the curtain pressing plates for the lead protective soft curtain are respectively arranged on the first section arm, the second section arm and the third section arm. When the first, second and third arms are on a straight line, the lead protective soft curtain is in a natural vertical state, and can effectively protect the left side of the operating bed during interventional radiation by matching with the protective screen suspended on the bed. The second section arm can rotate to drive the sliding rail, the third section arm and the lead protection soft curtain below the third section arm to rotate, and the height position of the second section arm is adjusted by adjusting the length of the connecting sleeve inserted into the center hole of the first section arm, so that the second section arm can smoothly rotate to the lower part of the operating table; then the right end face of the lead protective soft curtain at the lower end of the third section arm is just in close contact with the medical ray protective curtain hung on the right side of the operating table to obtain the best shielding effect by sliding the third section arm, so that the maximum protective effect on the second operator on the right side of the operating table is achieved.

Description

DSA operation table under and left side protection curtain

Technical Field

The invention relates to a protective curtain for a Digital Subtraction Angiography (DSA) operating bed (also called a conduit bed), in particular to a protective curtain under and on the left side of the DSA operating bed.

Background

The radiation intervention operation bed is provided with a bedside protective curtain according to the national relevant protection standard requirements so as to reduce the injury of X-ray radiation to an operation operator. The prior DSA operation bed side protective curtain is basically arranged and intervened on the right side of an operation bed, the protective performance of the first operator position on the right side of the operation bed can meet the protective requirement, but the protective performance of the second operator position and the left position of the operation bed can not meet the requirement specified by the standard because of the photographing position. In order to improve the protection effect at the two working positions, the company develops a protection curtain which can be placed under a DSA operation bed and can also be placed at the left side of the bed on the basis of the existing bedside protection curtain.

Disclosure of Invention

The invention aims to improve the protection of a second operator position when an interventional radiology operation is carried out on the right side of a DSA operating table under the normal condition or the protection of an operator when the operator operates on the left side of the DSA operating table under the special condition. The adopted design structure is that the first section arms of the protective curtains under and on the left side of the DSA operating bed are suspended on the guide rail on the left side of the operating bed; the second knuckle arm is connected with the first knuckle arm through a connecting sleeve and a pin shaft, and the upper surface of the second knuckle arm is lower than the lower surface of the first knuckle arm; the second joint arm can rotate to the position below the DSA operating bed around the connecting sleeve; the third section arm can slide on the slide rail to the length of the protection curtain that second section arm and third section arm were hung makes the protection curtain can contact with the medical ray protection curtain that the operation table right side hung when rotatory under to the bed, forms and shelters from the DSA bulb bi-directional, strengthens the protection to the operator when DSA operation table right side two operators position intervene the radiation operation. When the third section arm of the protective curtain under the DSA operating bed and on the left side rotates to form a straight line with the first section arm, the protection on the left side of the operating bed can be achieved, and the protection on an operator during the interventional radiation operation on the left side of the DSA operating bed under special conditions is met.

The invention relates to a lower and left protective curtain of a DSA (digital drainage bed) operating bed, which comprises a first section arm, a pin shaft, a connecting sleeve, a second section arm, a sliding rail, a third section arm, a curtain pressing plate and a lead protective soft curtain. The method is characterized in that: the second section arm is connected with the first section arm through a pin shaft and a connecting sleeve; the upper end part of the connecting sleeve is inserted into the central hole of the first knuckle arm; the sliding rail is arranged on the second section arm; the third section arm is installed on the slide rail, and the soft curtain of plumbous protection is installed respectively on first section arm, second section arm, third section arm.

Preferably, the first knuckle arm can be mounted on a guide rail on the left side of the DSA operating table to protect the left side of the operating table from radiation.

Preferably, the second and third articulated arms can rotate to the position below the surface of the DSA operation bed to protect the lower back of the operation bed.

Preferably, the height of the upper surface of the third arm section is adjusted by adjusting the length of the connecting sleeve inserted into the center hole of the first arm section, so that the requirements of different thickness of bed plates of DSA operating tables of various models are met.

Preferably, when DSA operating table and left side protection curtain rotate to operating table under, the size of protection curtain protection area can be adjusted through the slip of third festival arm on the slide rail, satisfies the requirement that various models intervene operating table bed board width differs.

Preferably, when the first section arm, the second section arm and the third section arm rotate to form a straight line, the protective curtains below and on the left side of the DSA operating bed can protect the left side of the operating bed, and the requirement of protecting an operator during interventional radiology operation on the left side of the DSA operating bed by the operator under special conditions is met.

Detailed Description

As shown in fig. 1, fig. 2, fig. 3, and fig. 4, in an embodiment of the present invention, a protective curtain under and on the left side of a DSA operating bed comprises a first arm 1, a pin 2, a connecting sleeve 3, a second arm 4, a sliding rail 5, a third arm 6, a curtain pressing plate 7, and a lead protective soft curtain 8.

When DSA is used for a radiation interventional operation, when an operator operates on the right side of an operating table, the second knuckle arm of the invention needs to rotate 90 degrees, and the height of the second knuckle arm is adjusted by adjusting the length of the connecting sleeve inserted into the central hole of the first knuckle arm according to the thicknesses of bed plates of operating tables of different models, so that the second knuckle arm can rotate to the lower side of the operating table; then the end part protective curtain is just in close contact with the medical ray protective curtain hung on the right side of the operating bed to obtain the best shielding by sliding the third section arm, thereby achieving the maximum protective effect on a second operator.

When DSA is used for radioactive intervention operation, when an operator operates on the left side of an operating table, the three sections of cantilevers form a straight line and are matched with a suspension protective screen on the operating table to form integral protection for the operator on the left side of the operating table.
